Prompt me?

The end is in sight for my RBB, so I wanted to ask if anyone has any prompts for my Avengers Assemble S4 Countdown fic? Because I have no clue what I'm going to write! Obviously, it'll be a shorter story as my brain is still fried from RBB . It'll be nice if it tied into a specific episode, too, like a coda, just because those are a bit easier :)
