One of the (many) things I adore about Halsin is the way we affect him. As he says, he's been around a long time, had numerous lovers...but we get his heart pounding? He was so nervous about us rejecting him when he confesses? And when he accidentally transforms during the romance scene, he thinks he's ruined this moment with us that he's been dreaming about for so long?
And I'm trying to remember exactly what he said...it's in Moonrise right after you beat Ketheric.
"And I'm glad to be had- glad to be with you, I mean."
This may have nothing to do with what I said above, but I dunno. It stuck out for some reason. He's quick to correct himself, and it sounds like he's trying to play it cool. Trying not to reveal his feelings just yet.
He's just so cute sometimes.
