Help me figure something out? I think my canon Dalish fem-elf may have somehow ended up in a "it's complicated" threesome with Cullen and Sera, and I'm wondering if it's because I didn't actually max out Sera's approval. I flirted with both Cullen and Sera quite a bit, but since Sera didn't like me and kept saying something about travelling together, let's wait and see, I ended up pursuing Cullen instead.
Here's the weird thing: advanced Cullen's romance all the way to the end, got Sera's main quest finally, got friendly roof time and ignored all the possible flirts because, tempting as it was, I'd feel bad about dropping Cullen (and I don't think I'm supposed to be able to break up with him at that point). Then towards the end of my playthrough (post-Well-of-Sorrows, I think) I got one final flirt option with Sera. I thought, why not, and took it. My Inquisitor said something like, "whatever we are, it's fine, Sera," and Sera agreed in an oddly wistful way. It was actually really sweet - I wish I could remember the exact words. And it was definitely 100% a flirt icon, not a broken heart or anything else. After that, I went on and finished the game.
Is that supposed to be some flirt that happens before locking in Sera as a romance option? Was she supposed to issue an ultimatum to get me to break it off with Cullen at some point? Did I miss part of her content that was supposed to unlock when she liked me more? I know I lost a bunch of approval over the course of the game, but I figured that post-cookies and pranks, we were pals... and apparently in some kind of star-crossed romance.
