Young Avengers/Tear Jerker

• The scene at the end of the second arc, in which Hulkling scatters his mother's ashes at the Avenger's Mansion.
• Another one in Young Avengers Presents #2, which is also Hulkling-orientated, where his biological father, Captain Marvel, apparently came back to life through a time skip just long enough to meet up with Hulking and find out Hulking is his son and they share a touching moment where Captain Marvel promises if he has time before having to go back to his own time just before he dies he'll spend it with Hulkling but the sad part comes when on a rather beautiful panel and a page before it, where Captain Marvel flies off and they share a rather touching moment.

Hulking's thought bubble: For just a second, I could pretend I had a Dad. I could pretend I'm not alone in the world. For just a second.
Captain Marvel: I will see you again... If I get the chance...Before I return to my own time.
Hulking: That would be nice. (Thought bubble) And it would have been nice... But I never saw him alive again.

• Children's Crusade #8 gives us Cassie's death. Issue 9 follows up with Iron Lad killing Vision II in cold blood, and the rest of the team opting not to restore him from one of his back-ups, as that would mean they'd have to tell him that Cassie was dead.
