There's a brief, petty moment where Alec shoots a look at the nearest cat when Magnus runs his fingers through Alec's hair and he nearly purrs, making eye contact with the cat he's pretty sure responds to Church, as if to say hah when he's the only one to receive the attention.

Alec is listening intently, watching Magnus' lips move as the words settle in and he's only half-formed the thought to definitely move to a different chair when Magnus sits on his lap and effectively narrows his thoughts, whether deliberately or otherwise.

"Well, that explains a few things," he replies with a small smile, his arms gently settling around Magnus, fingers still threaded through his keyring. He's more than halfway through considering kissing Magnus good morning, but holds off just long enough that Magnus continues speaking.

Alec never looks away from his face, even as he notices Magnus glancing to the keys dangling from his hand.

Fortunately, the keys are on the hand tugging Magnus just a little closer, which leaves his free hand to reach up and cup Magnus' face gently, always gently, aware of his own strength to a fault. Alec is smiling before he realizes it, bright and real and absolutely unable to hide the depth of the warmth spreading through him at the invitation Magnus just extended. Even if it feels a little like he's still expecting Alec to spook at some moment... maybe that's fair, considering the conversation Alec was just having with the cats...

"I'd love to," he answers, before Magnus can back out of it, or give him an opening to do so himself, stroking his thumb over Magnus' lips without thinking. "I don't... think I can full time. You're right, I need to be present at the Institute, but I'd-- I'd really like to be here. More. With you."
