Blaineley is obsessed with gossip and fame. She wants more than anything to obtain a "juicy" story and attempts to delve into topics that could potentially cause a scandal. When she first appears in Celebrity Manhunt's Total Drama Action Reunion Special, Blaineley is depicted as enthusiastic and friendly; however, her true colors are eventually revealed when she starts hosting Total Drama's Aftermath show.
On the aftermath show, Blaineley demonstrates that she is conceited, mean, and willing to do whatever it takes to remain in the spotlight, including sending Bridgette to Siberia and lying about her real name. When she joins Total Drama World Tour as a contestant, it doesn't take long for the others to start hating her, but a different side to Blaineley is shown when she is paired with Owen in Niagara Brawls. Through an unlikely friendship, Owen helps Blaineley let loose and focus less on her public image, proving that she isn't entirely bad after all.
Blaineley's first appearance is in Celebrity Manhunt's Total Drama Action Reunion Special, where she hosts a talk show called Celebrity Manhunt alongside Josh. During their exclusive on the Total Drama cast, Blaineley shows enthusiasm for each of the contestants. She is very excited to meet Lindsay on the red carpet, whom she labels as the "fashion goddess" and says Lindsay has always surprised her with her incredible looks and designer dresses. However, Lindsay later fails to wear anything fashionable at all, since she believed it was a dress rehearsal, and is only wearing her regular outfit with new earrings. Blaineley comments on how she definitely will not be asking Lindsay for fashion advice.
While commenting on Heather and Gwen's blog wars, Blaineley states that she's on "Team Gwen", since Gwen is "weird and awesome and the total anti-Heather". Blaineley also admits that she has a "crush" on male model and former castmate Justin, whom she says "had enough flavor for all of The Drama Brothers". When discussing Leshawna and Tyler's reality show success, she explains that Leshawna's worst career move was her "Largest Loser" weight loss show appearance as she wonders why Leshawna trimmed down her "perfect booty". After Sierra becomes a Celebrity Manhunt interviewer, Blaineley complains that Sierra wasn't "digging up the dirt" with the former castmates on the red carpet and she slowly grows irritated with Sierra's amateur gossip skills. While the bus chase between the Total Drama cast and the cast of Total Drama Dirtbags ensues, Blaineley is shown watching it intensely along with Josh, eating popcorn as they watch the cast head towards a cliff. After informing Trent, Geoff, Justin, Beth, Katie, Sadie, and Eva that they did not make it to season three because they left the main group and returned to the studio, she tells the public that she, along with Josh, will tune in to watch it. This enrages Eva to the core to the point that she has a temper tantrum and trashes the Celebrity Manhunt studio.
After quitting her position as co-host of Celebrity Manhunt for unknown reasons, Blaineley joins Geoff in hosting the Aftermath show, replacing Bridgette who is competing for the season. In a similar fashion to Geoff's "Captain Hollywood" moniker last season, Blaineley attempts to stir up some drama between the contestants in order to boost the shows ratings. It is this difference that she clashes with Geoff throughout the season.
During the first aftermath of the season, she clashes with Geoff as she keeps pestering Geoff about Bridgette cheating on him with Alejandro, but he pretends to not care. In order to bring more drama to the show, Blaineley attempts to bring Bridgette in as the first guest but Geoff delays it by introducing Harold first, much to her displeasure. Even after Harold is interviewed, song and all, Geoff still refuses to speak to Bridgette and plays the "That's Gonna Leave a Mark!" segment to stall her introduction. Blaineley finally stops the stalling and manages to call Bridgette to the studio, but she refuses to come out. Eventually, Blaineley gets her drama, and raises the tension by showing the scene of Bridgette kissing Alejandro and having a video guest remind her of the situation. Aggression builds up between Bridgette and Geoff, and Blaineley seizes the opportunity to start a new segment called "Total Smackdown", in which Bridgette and Geoff are put in a boxing ring to fight. However, the two shortly forgive each other and start making out once again. Angered that her plan failed, Blaineley begins to throw a tantrum and has to be escorted out by two interns, with Blaineley quitting the show and vowing to return to Celebrity Manhunt.Despite her promise in the previous aftermath, as well as Bridgette regaining her spot as co-host, Blaineley continues to host the show alongside Bridgette and Geoff in Aftermath: Revenge of the Telethon. It turns out that she attempted to regain her position at Celebrity Manhunt but gets turned down. Blaineley attempts to help the Peanut Gallery raise money but only causes more trouble. Her plot entices donations by forcing DJ to face the animals he harmed in the season backfires and causes their goal to increase from $500,000 to $1,000,000. Eventually, Blaineley is tasked to answer all the calls after Geoff takes the Peanut Gallery somewhere else for the final stunt, putting Brainzilla (Izzy's new persona) on a quiz game. After the aftermath is destroyed by a bomb detonated by Izzy and the goal is reached, Blaineley calls her agent and tries to cancel her contract with the show. Her make-up has rubbed off at this point, making her look disheveled, and she screams in horror when she realizes that the camera is still running.
In the beginning of Aftermath Aftermayhem, Geoff reveals that Blaineley has become a roving reporter, traveling around the world in search of her number one fan. Much to everyone's surprise, Blaineley shows up at the studio and reveals that she made Bridgette take her place. Angered, Geoff swears revenge on Blaineley and proceeds to embarrass her by showing behind-the-scenes clips of her and singing a spiteful song about her, revealing her real name is actually Mildred. During the Second Chance challenge, Blaineley attempts to get the five contestants to either complete their challenge fast or get eliminated as she tries to get the show to end quickly and collect her payment. Beth ends up reaching the final question, but has trouble remembering what the name of Duncan's London-based punk band is. Desperately trying to end the show, Blaineley urges Beth to say it's "Der Schnitzel Kickers", which results in her giving the right answer. Taking advantage of the moment, Geoff gives the reward to Blaineley, who runs away in anger. She is then tied up by the interns and sent off to compete along with the remaining contestants. In an exclusive clip, Blaineley is shown complaining about having to compete on the show while being flown to the destination, Niagara Falls, in a small box.
Blaineley makes her competition debut in Niagara Brawls, singing Blainerific to establish her entrance. Her appearance shocks the remaining contestants as most of them believed that Gwen will be returning. She is partnered with Owen for the challenge, who she believes will help improve her image on the show due to his popularity. During the tightrope challenge, she gets into an argument with Sierra which leads to their teams falling and being eliminated. At the elimination ceremony, she starts crying over Owen's departure, calling him her "Chubby Hubby". Immediately after, she reveals that she is only doing it for the publicity.
In order to ensure her victory, Blaineley requests Chef Hatchet to form an alliance with her in Chinese Fake-Out. Though Chef has some doubts over the plan due to his failed alliance with DJ last season, he finally agrees. With Chef's help, Blaineley easily completes the racing challenge after Chef pulls her to the finish line faster than the others. During the eating challenge, she has Chef secretly serve her decent food as opposed to what the other contestants had to eat. Eventually, Heather catches her in the act and she is forced to swap meals with Sierra. Because of this disadvantage, Blaineley loses the challenge. During the elimination ceremony, Blaineley receives the same amount of votes as Courtney, but instead of a tie-breaker like before, Chris decides to eliminate the both of them in order to save the show's budget. Before she takes the Drop of Shame, Blaineley angrily reveals several secrets; Alejandro and Heather are in love with each other, Cody has been voting for Sierra in every elimination ceremony, Ezekiel is still been hiding in the cargo hold, and she was originally intended as the host of the show, but it was instead given to Chris. Infuriated, Chris pushes both her and Courtney off the plane.
Blaineley is introduced as a guest in Hawaiian Style, and is now wrapped from head-to-toe in bandages and supported on a dolly. Geoff reveals in a video that after taking the Drop of Shame, Blaineley failed to pull her parachute and crashed into a Chinese hut, resulting in her current condition. She is initially the only person to support Heather, but only because of Duncan putting a Heather flag into her sling. She is also forced to compete in the challenge, with Owen being the only person to have pity and volunteer to help her. Owen uses her as a surfboard but ends up sending her flying into the ocean. Bruno, the bear Bridgette befriended in Siberia, rescues her by carrying her in his jaws to shore. At the end of the episode, Bruno is seen gnawing on a terrified Blaineley's head.
In Hawaiian Punch, Blaineley is still wrapped in bandages and supported on a dolly. At the end of the episode, after the volcano erupts, she is seen rolling down the volcano behind the other contestants, as well as running over Alejandro.
Blaineley makes a brief cameo in an exclusive clip for Evil Dread in France. She appears with Bruno in a swan boat, knocking Lightning out of the boat's path. Judging by this clip, it seems as though Blaineley recovered from the injuries she had the last time she was seen.
In A Million Ways to Lose a Million Dollars, Blaineley makes a brief cameo appearance outside the Empire State Building. She is seen carrying a large amount of shopping bags and boxes, while walking past Sanders and MacArthur. In this brief appearance, she is wearing a pink dress rather than her usual red dress.
