It really did a number on him to have her pouring out her anger in their shared lip lock. It drove him batshit insane is what it did! He didn't care that it'd be posted in the gossip column of The Daily Prophet, it wouldn't be the first time he was caught kissing a girl in public. What he did care about was getting out his own anger through the act, and surely he did with the way he grazed her bottom lip with his teeth and how he practically lifted her off her feet to kiss her harder.
It sure did get Patty's attention. In no time the girl was hopping mad and tugging on Marcus' elbow. Marcus finally let the waitress down and found Patty was grabbing at his arm and heading to the exit. "Honestly, bay-bee, I was jus' havin' some fun and you go and start kissin' the first girl you run into!"
He didn't bother arguing, or saying anything. He simply walked out with the girl he came with, feeling all sorts of strange in his gut.
