Marco was telling Cathal about a series of not quite fully legal shenanigans he'd been involved with in high school (involving breaking into the school and many teachers' shoes) when Cathal caught the movement of someone in the doorway.
At the sight of Marcie, Cathal's eyes widened and his mouth opened a little. She looked- she looked really really great. Any chance that was for him? Cathal didn't want to assume but... he really wanted this to be for him.
He composed himself to smile at her and said, "afternoon, Marcie."
