"Oh, hell no." Magnus says as him and izzy walk in the ops center.
"What's wrong?"
"Who is that talking to Alexander?"
"That is abby nightcloud. She just joined the new york institute."
Before magnus can say anything else, abby reaches up and touches alecs cheek. Izzy looks over at magnus and sees blue sparks coming from his fingers.
"Magnus, you cannot attack a shadowhunter in the institute."
"No, but I can show her what's mine."
Magnus leaves izzy standing in the door and walks over to alec. He puts his hands on alec's hips, leans down and kisses his neck.
"Who are you?" Abby asks, pulling out her sereph blade.
"Abby, this is my boyfriend, magnus."
"He's a warlock."
"I know."
"You are dating a warlock?" She asks, hatefully.
"Yes, i am. Actually I am dating the high warlock of brooklyn." Alec says, kissing magnus.
Magnus deepens the kiss while alec tangles his hands in magnus's hair. Alec pulls away, looks into magnus's eyes and seeing the warlocks smirk, pulls him out of the ops center and up to his room.
