In off stars Courtney was put on the heroic hamsters until saving private leechball when she switched teams with Duncan. Here are some reasons-
Wasn't an antagonist in island
The writers forgot about her being an antagonist in action
Her boyfriend was 'stolen' from her ( why the second half of I see London stinked)
. Yes I am confused why she was on the heroes team in the first episode of off stars. Another reason why the season was terrible.
