Phil/Natasha
I'm not entirely sure how it went. He was pretty down when he came back. I haven't pressed him about it, he'll tell me when he's ready. Thankfully I haven't seen much of Tony and I'm not complaining.
Wait? You want a chance with Peggy? I did not know this. Honestly though I don't know. I've only talked to her the one time so I can't hazard a guess as to what she thinks. I suppose it depends on what Tony told her. That could be just about anything.
