Scarlett, Heather, and Bridgette are also my favorite characters. I've done my username and rankings. Here are my opinions for them:
Scarlett: She was very dramatic and amazing this season. The episode "Scarlett Fever" reminds me of a song "Night Fever" by the Bee Gees. That episode makes Scarlett the main character of the episode and wow, the develop of her was excellent.
Heather:When I first watched Total Drama Island, I use to hate Heather, but as the process goes on, I started to like her, In TDWT, she was pretty hilarious and smart player.
Bridgette: She was the nicest of all in TDI. I was a bit shocked to see her eliminated in "Hide and be Sneaky" In the Aftermath, her hosting was amazing. You know, I wish in the future season, Bridgette could make it further in the game.
