After Skaar attempted to kill the Hulk, but then reverts to human form right before the Green Scar is about to strike him in retaliation, this reminds Green Scar of his own abusive father. The Green Scar immediately turns back into Bruce, and he and Skaar finally hug each other as father and son. Also overlaps with Tear Jerker, after seeing the flashbacks to Bruce's own childhood.
THIS◊. note Sadly, it's from an alternate reality, and it eventually doesn't really end well, either. Doctor Doom of this reality transforms Bruce and Betty's son, Skip (a.k.a. Skaar of this reality), into his Hulk-like form, and his mother is forced to kill him.
