OMG, somebody totally needs to write a drugged!Marcone fic where he spouts that line. Srsly. I'd love to see Harry's reaction to Johnny-boy cuddling up to him, saying lines like that to whatever fae/wizard/whomever is trying to kill them. Or enlist them. "No, he can't work for you. He's mine."

That is totally priceless. Thank you for that.

(Of course, now I can't keep "just keep swimming" out of my head!)
