I love both scenes, and how they encapsulate so much of this relationship. First, the way that Dick and Tim actually *talk* about a lot of things and Dick cares about how Tim is handling this stuff. He berates himself for "seeing what he wanted to see" in not realizing how close Tim was to the edge here to begin with, but there's also an earlier story where Tim says he talked to Tim about all these deaths a lot and it was talking to him that got him to stop feeling like every life he touched died etc.
Anyway, so I love how these scans just so so much trust, both in the way Tim can talk about this stuff, and how Dick has to let him make his own choices. Their fight in the recent RR totally echoes this one, with Tim telling Dick he needs to trust him and Dick again extending the trust.
Plus, hair-kissing. It will never get better than the hair-kissing.
