Jeff's interactions with Mimi, trying to undo some of the damage Him did to her.
Minnie and Junior being so much closer after her death and resurrection.
YMMV, a particularly odd one for Mandy, that comes right after her MEH of beating up Junior. She neither kills Junior or Mimi and even congratulates Junior for standing up to her!
A rather strange one, Him has a picture Dexter, Blossom, Bubbles, Buttercup, Courage, and Mimi together. He drew mustaches, silly eyes, the usual stuff one would do to make fun of people, but for Mimi, he just drew horns. Make of that what you will.
When Aku takes Chi away to 'discipline' her, he begins by giving her a lecture...demands that she looks at him when he's talking to her...and then stops her from crying by pulling the most ridiculously funny faces. It's implied that while far from ideal, Aku clearly dotes on his daughter and their relationship is a lot healthier than the ones between Him and Mimi, and Mandy and her children.
Jr. and his Nergal symbiote seem to be getting along quite well since the big incident.
