Here he stands again. Watching you from his tent, just looking as you help Gale with another spell he needs a tester for.
Seriously, Astarion can't stand you- well himself anymore. He wasn't supposed to actually like you. This would have to be like always. Just get you to like him so that he's guaranteed safety.
But no... now he's the one liking you. Rather much, actually. Like crazy much. And he knows that about himself since this annoying little jealous feeling has made its entrance in his vampiric heart...
"I can't believe this..." Astarion mutters to himself as his red eyes follow your form. Is it bad to genuinly love someone for once? Can't he just keep you for himself? As a little cheering up gift from the gods after he suffered for years under the hand of his master...?
