1.

Jason, Dick, Damian, Bruce and Duke having lunch at a Bat-burguer place (where they have red hood action figures and jokerized ships, that Jason wants to try). 

2.

the way Bruce eats a hamburger and the fact that the boys make fun of him for it (plus Damian trying to kill Jason with food).

3.

the way they talk about their deaths as it was nothing, and Duke being the only one who realizes thats not normal. 

this hole issue was just like a big fanfic and I love DC for it.
