Lets summarize what we have about poly/mono things in act 1-2: 1.)She shows NO interest in poly relationship if asked directly. Thats just it, stop trying to headcanon anything. 2.)She is flirty but won't sleep with others if not romanced/shows no interest at others. 3.)The only indication that you can classify as "poly" - at tiefling party where she says "not today" if you ask her about sharing a bottle with all friends. But, I may be dumb, how the hell you came into this conclussion. I even rewatched this scene and it's just blatant that she wants you 1v1 and it's funny dialogue choice to play dumb? It doesn't even end with sex or anything.
Lol. We're both "headcannoning" here. We have different interpretations of the party conversation - I don't think it's playing dumb I think it's being playful. We don't see Tav's facial expression but I imagined that Tav was trying to suppress a grin when asking "just a bottle"?
This is what flirting looks like. You are talking about sex and relationships while ostensibly talking about wine.
