after so much time in the KND, Wallabee is finally close to 13 years old, which depresses him and he constantly hates being reminded of it, you were his colleague in sector V but he hated you just because you are a year younger than him, and he knows that he will forget you and all his adventures with you, forming a feeling of sadness and hatred

now, they're in the treehouse, for missions, no sector member is more than you and Wallabee who tries to ignore you as much as possible
