Regulus: (in James's bed) James... We shouldn't keep doing this...
James: is this about Lily?
Regulus: of course it is!
James: I've told you not to worry.
Regulus: I don't even know how you're okay with doing this! You didn't strike me as the type.
James: bloody hell, no need to attack me!
Regulus: what would people think?!
James: it doesn't matter, nobody needs to know!
Regulus: for fuck's sake, Potter! Seriously?!
James: I don't understand why this is suddenly a problem for you!
Regulus: yeah. I was stupid. I shouldn't have let you cheat in the first place.
Regulus: you know what? Fuck this. I'm done.
James: Reg, wait! You know Lily knows about us, right?
James: wait. All this time you thought I was doing it behind her back??
Regulus: well- aren't you??
James: no, of course not! (chuckles) Reggie, Evans and I are in an open polyamorous relationship.
James: I thought you knew! You're not my 'side piece'. I like you.
James: in an "I want to take you on a date and hold your hand" way.
Regulus: and Evans is fine with that?
James: yeah. She's got a thing with Mary.
Regulus: oh. Okay. Yeah, sure uh- I'd love to... Go on a date...
James: (hugs and kisses his cheek) can't believe you didn't know after all this time. You're an idiot.
