As Lily walked over, Kris relaxed his shoulders and leaned back, an amused smile dancing on his lips. In real life he spoke, "Why hello there, Ms. King, nice of you to join your boyfriend for a tutor session. Psy - excuse me, Angelo just needed some help with Literature before a...festive appointment this afternoon. I don't believe women were invited, unfortunately."
He listened to her direct proposal, and slightly expected/surprised she knew by coincidence/deduction what the private conversation was about. Not breaking stride, he slowly put a finger to his lips and replied, "Hey now, education isn't the proper setting to talk about trivial matters like video games, especially when I'm the tutor. Maybe later online, when we can have a heart to heart on other matters, if you want."
He winked at her with his right eye, and glanced out of the other at Psycho, waiting for his response.
