1. AA gave no comment about Tav leaving with Karlach or Lae'Zel back in Patch 5, so it doesn't count. His epilogue with a mindflayer Tav makes it look like he is together with them, but it's obviously just a bug. So, the same situation could have been there.
2. Tav is not a vampire bride. They are his Spawn. Confirmed by devnotes and other flags in the datamined files.
It's Larian's canon. Also, AA compels Tav to stay with him when they want to break up in the end. Also canon.
3. For the sake of this argument, let's pretend that Tav is a vampire bride, even though it's not true. Then what, are you saying AA is a good partner for literally gaslighting Tav into thinking they are his slave, because they can't leave him without his permission? "You didn't leave me, I let you go." Nope. Still abuse either way. Still lying to them to deny Tav their freedom.
