Chris hugs Levi tighter and tries to nuzzle his cheek against him while Levi's trying to nuzzle his nose. He dramatically proclaims that no - Levi is his best friend and that means a lot to him, he's gonna break Levi's nose in the future at a later date, yet to be determined, but it'll happen, because this is their thing, and he's really gonna miss their thing when they graduate. Somehow in the midst of all that, he ends up also acknowledging and admitting at the same time that he's gonna miss Levi too.
