I always thought a fun idea for an Gleevengers AU would be one where Blaine is Tony Stark’s son (as is tradition), but we find out that Captain America has either a son or a grandson (I have no idea how. Work it out). His name is Sebastian Smyth.
It would be very interesting to see Boyscout Steve deal with Sebastian. Not fuzzy, woobie, edges sanded down, I finally realized I’m a horrible person Sebastian either, but “I Want You Back,” creepy as hell, do what I want to get what I want Sebastian.
Just because you share a blood connection with someone doesn’t mean you are going to be anything alike. How the hell would Steve deal with kid like Sebastian? Especially if said kid started making creepy as hell moves towards the son of one of his co-workers. Specifically, the one who happens to be Iron Man. Who probably gets Sebastian on a level Steve wouldn’t, and who probably won’t lose a lot of sleep over taking Sebastian very high up into the air and dropping him.
