I mean….I never rule anything out because at the end of the day, these aren’t people with their own thoughts and wants, they’re fictional characters the writers move around for maximum entertainment and drama, so I can’t say that they might not go for some super ill-conceived awkward threesome but even then, I can’t imagine it’d be for any purpose other than to show how awful an idea it would be.
For one thing, the show’s made clear that April’s a lesbian and that she’s actually okay with it. So I don’t know why she’d even do that. Even if there’s some attempt to basically conversion therapy her, or something for appearance’s sake to put her dad off the trail, that is the absolute worst message the show would want to go with. Secondly, even if it were like, uh, a V, so no April/Luke, the show has ALSO made clear that even though Sterling is most likely bi, she’s not actually in love with Luke, at all. If she can be with April, there’s no need for her to be with Luke, she only kissed him because she was heartbroken over April. She’s not equally torn between the two and can’t choose. Like, if the April/Sterling leg is on, as harsh as it is to say, there’s no need for the third point. Also, lastly, even if it WERE for appearance’s sake, a threesome would be super scandalous on its own in this community and would not actually fix anything they’d want fixed.
So yeah, it’s possible, but then so much would have gone wrong with the writing to get to that point that I’m not sure I’d care specifically about that anymore, you know?
