Okay, so we didn't get many Tripkey moments, but I see this season as a building block for their relationship. They're just getting used to each other, becoming friends, which is such a big step for Monkey. A HUGE step. They are wildly different which causes them to butt heads (especially regarding Monkey's inflated ego) but they challenge each other, inspire one another.
Monkey felt so grown up in that last scene they shared. The lengths he would go to protect her was so sweet to see, and Trip's declaration that she would sacrifice herself to bring him back was a wonderful moment as well.
Fingers crossed for a third season, because after that emotional goodbye, we be getting some good ass angst my guyss.
