The most revealing detail is how the second character feels about him. For me it reveals that he must be a character full of contradictions. This was established earlier, but the last couple of sentences really show that the narrator's feelings for him are just as diverse as all his traits.
I would love to know how this character feels about the narrator. I already feel invested in the characters through the few lines of description, but I would love to read more about their friendship.
I really enjoyed this small descriptor and I hope I read more about those characters in the future!
