Obviously it's possible, because he can't compel Tav while the tadpole is still in their head. He never compels this Tav because they literally never stay with him alone in the end if they broke up previously. And if he tried to do it in the presence of other companions, they would have defended Tav and kicked his bottom for it. This perfectly explains why he only forces Tav not to break up with him when they do it in the end, when they are alone with AA.
Confirmed by the epilogues, if you attack AA at the party, everyone joins you against AA.
My whole point is that PC has had *months* without the tadpoles protection at that point and he doesn't force them to join him. Neither does he attempt it at the party.
Oh man, I love his line about missing Tav and admitting he's lonely. Especially in the face of how hard he copes when he's first dumped, acting like it'll be so easy to replace the PC. Only to show up six months later and swallow his pride enough to admit he didn't. The voice acting is great there. You can hear the bravado, mixed with a tinge of nostalgia.
BUT that brings it back to the relevant topic of the thread. I agree with @celesti. I'm actually surprised how...non-possessive he can be as a Lord. I wouldn't mind him being a tad more vampiric and obsessive in the face of poly scenes and dialogue. I'm surprised AA is so permissive and "do what you wish" with Tav. Compared to normal vampire lore, he is pretty soft with the PC. Not necessarily a bad thing. But couldve been fun to lean into the obsessive nature a bit more.
Yeah the cope does make me chuckle. Man went full "I'll have another you by tomorrow" then had to choke on his words later. I do respect him for being real enough to admit it though.
I like yanderes but I don't really feel AA would be one? Like I dunno he doesn't give me the possessive vibes personally.
For me a yandere Astarion should've jumpscared my dumped him spawn at the ending. XD I didn't get that.
