Hi Charlie! I hope you're excited, I'm excited! I'm Harleigh and I play a few people, but first, if you don't mind me asking, are you a dude or a lady? Charlie could go either way, you're an enigma.
Okay characters: I've got Agent Sitwell, Mockingbird, Daisy Johnson and Iron Man. I guess Sitwell wouldn't know Bucky yet but !!! that's something to look forward to? Right now, he's also putting together Nick's Howling Commandos PMC, though, to do kickass stuff on the downlow and Invaders are always welcome. Also,sorry for stealing Steve's face. Bobbi's just become Mockingbird and is presumed dead and living under a new name in New York and getting used to this costume thing, so she and Bucky might have a few things in common to commiserate over. Or they could run into each other in a dark alley and hit each other over the head. Daisy, right now, is still an agent of SHIELD under Hammer's command but is really just waiting for him to kick her out. Then she'll be in the Secret Warrior's base in New Mexico? Nevada? Some desert that I don't remember right now. So also a Commandos friend. Aaand Tony. Since your Bucky is coming in under slightly different circumstances than 616, the animosity between them might not be so terrible. But it probably would be because Tony's an ass. They'd probably meet through Steve or Natasha, though, right? Don't worry about him.
This is too much information, I'm sorry. Have a seat, have a drink, tell me about yourself.
