Look, I’m not opposed to Stormpilot, but at the end of the day I never picked up on any signs, and I say this as a Reylo fan. Maybe I’m just too straight to ever pick up on gay hints. Harley and Ivy seemed outta nowhere to me in Harley Quinn so…
Haha! Okay, rewatch some of their scenes together… the way Poe bites his lip while examining the fit of his jacket on Finn is where it all started. A lot of their interactions are very comfortable with each other.
Oscar Isaac said “Personally, I kind of hoped and wished that maybe that would’ve been taken further in the other films, but I don’t have control. It seemed like a natural progression, but sadly enough it’s a time when people are too afraid, I think, of… I don’t know what. But if they would’ve been boyfriends, that would have been fun.”
Boyega said “They’ve always had a quite loving and open relationship in which it wouldn’t be too weird if it went beyond it.”
As for Harley and Ivy… that one has been in the cards and hinted at since Batman: The Animated Series, where Ivy helps console Harley to not need abusive men in her life. It wasn’t overt until much later in the comics, but it definitely has a lot of foundation.
