I haven't followed this discussion super closely recently so pardon me if I get something wrong, but there's an aspect of this whole situation that I do find pretty weird. I don't know polyamory super well personally, but I have known one or two people who are polyamorous, and I've seen discussions of it with moderate frequency elsewhere, so I'm not speaking in total ignorane when I say that in general, a polyamorous relationship doesn't strictly mean that the people within it are seeing other people at that exact moment. Two poly people don't stop being poly if they're only in a relationship with each other for a while. Halsin saying that you have to be actively pursuing someone else to be with him seems strange to me in light of that. It doesn't seem crazy to me that he would just be with Tav and be fine with only Tav for like, the week or two that the final part of the game seemingly takes place in? It's not like prior to that he's expressed strong emotional connections to any other companions that he'd feel compelled to pursue, and it's not like he'll have a lot of time to meet new folks while he's busy saving the world with us.
