You were... timid, to say the least, so when H announced the first challenge to be an obstacle course, you mostly freaked, though the one who can be considered a team leader in a way, Stuffy, decided to help! And so she offered for you to ride on her back while she jumped, with you replying- "Why should I trust you?," and her replying- "Hey, hey, it's okay, I just want to help!" It is now your decision whether you want to accept it, or alternatively decline the offer.
