A hint of selfish gremlin behavior, then a pitiable backstory where we learn that she hasn't had arms since elementary school. (By the way it took me two reads to notice that she didn't have arms in the flashback. I was really confused).

Now this will he a good opportunity for clinton to share the story about the firecracker and for them to bond over childhood injuries.

If i were writing it I would iuse it as an opportunity to frame it as Clinton taking the hit to save Claire though she doesn't know it. Inspiring Luz to tell her arms story or if there is no story and she never had them and se talkscabout how annoying it is when people ask. Then it ends with liz giving claire a drunken punch in the arm with a "be nicer to your brother"

However this is unlikely. Because it would would mean addressing a flaw with claire
