Even the hardest men cry when someone so dear to them passes away, I'm pretty certain of that because I've known of it.

I'm not talking a stream of tears, though. I'm personally much more likely to get a burning sensation around my eyes with a lot of salt but not much water. I don't get teary, I just get wet, burning eyes... if that makes any sense. So maybe he gets that way, where he just doesn't find crying to be something that comes to him anymore, even if he feels devestated at the time.
