I love Kate :D And that idea is fun! You should write that idea *evil enabling grin*

But my brain mashed it with the whole Clint High School foster genre and...what if being fostered didn't make Clint all scruffy clothed and bullied, but made him not stick out at all? And he enabled that, because he wants to fit in. And that makes him invisible. And things happen and he ends up at the school for invisible people, which is probably SHIELD run in my head, and there he meets Natasha.

(Although my first thought was straight-up, Macey's story. But I cross and fuse everything with Clint/Natasha in my head these days lol.)
