It's amazing, really, just how awesome they all are. All of them. Everything they do, or don't do, is just so amazing/funny/sweet/heartbreaking. Even the side characters, even though they aren't around enough yet, are incredible.
Roy was back in this volume - that makes me happy. And Hawkeye has a first name! I'd wondered what it was.
And the flashbacks and training scenes were just....ahhh, I keep using this word, but they were awesome. Everything about this volume was awesome, from one end to the other.
....DANG, BUT I LOVE THESE CHARACTERS.
