"I have a vested interest in getting you off."

 

Sigefrid hasn't met Sebastian as himself!!! but Serena is already committed to protecting and nurturing him! 

Sebastian: just Lincoln Lawyering in like "hi yes hello he's innocent!"

and Sigefrid just like "um... Wha-- who??? Bzuh? who the FUCK are you!?"

"I... That... is not important right now! What is important is that...." Sebastian slams hands on the table like an anime character. "I have a vested interest in getting you off, sir."

(Ultimately, we decided to go in a different direction, but this was too funny not to share.)
