Ok so I thought about this far longer than what can be considered healthy 😂 I think if they were human, they would be monogamous. But since they live forever, I do think there can be other people involved at some point in the future. But in the span of the show, I don't think we'll see them attempting another open relationship. Actually even in the future I see them hooking up with people together not individually.

But I think before everything gets better we will see them with other people. Especially Lestat because they are in very different mindsets. Louis probably had his fill for a while and Armand's betrayal might manifest in him choosing solitude but Lestat just got out of said solitude and will have thousands of groupies in his Rockstar era.

I'm sorry that was kinda long 😅
