(I think he should find out later. Like, when they're kissing another time or something...)
Tristan, noting the odd actions with mild surprise and high curiosity, pulled back. He frowned, arms squeezing her shoulders. "You okay?" he asked quietly, gold-crimson eyes almost like a liquid, melted gold that had been in the middle of a vicious fight.
It was just then that Alix entered. He still wasn't wearing a shirt - His muscled chest shone brightly in the sun. He walked through the door, in too much thought to register that Tristan would be here before he got here. He glanced up, easily hiding the guilt in his eyes and replacing it with a cold, emotionless glare. He shook his head, huffing lightly. "Record timing." he growled to himself, moving past them and silently gliding up the stairs in the blink of an eye.
