By the way, since we're talking about DU and Astarion. (I write using a translator)
Our main character is an extremely cunning character. If I'm not confusing anything, he's the one who started this whole quarrel with Absolute. Just imagine how strong his brain must be to come up with all this, apart from stealing the crown from Mephistopheles!
And so, a romantic scene with the ascended Astarion. In which our character is given no choice but to obey or "hit the bells."
One more time.
A character who literally can become the personification of the term "punitive diplomacy", whose tongue is longer than that of a woodpecker, whose intelligence was recognized even by an Elder Brain (!).
Can not.
To talk Astarion down.
The same Astarion who, after ascension, does not think at all. He is literally too intoxicated by the prospects he has imagined for himself to think properly. I definitely do not have the opportunity to convince Astarion in that scene so that he would hold back his offer of eternal life until better times.
For the sake of space! You can force him to accept the astral tadpole, but not to maintain a relationship without becoming his spawn!
If I missed the opportunity to do as I indicated in the spoiler, please tell me.
