If possible, Greg's frown just deepened at Stacey's words. He considered just walking away, but from looking down at Stacey like this he could see dark ink on her hand, wrist and beneath her hair. He wasn't a stranger to tattoos - Marcus had recently invested in one - but he still associated them with the dark mark, especially ones that weren't brightly coloured. To Greg, the tattoos marked Stacey out as not some boring, insufferable Gryffindor and so he decided to stay, at least until she actually insulted him. "I wanted a pastry," he said, his only offered explanation for not smiling. He'd wanted a pastry and now he couldn't have one and he'd have to go back to work on an empty stomach. What was he supposed to smile about anyway?
Not entirely sure he knew where Puerto Rico was, Greg just shrugged. "At least it's not raining." Then, even with magic, it would be uncomfortable to sit on the ground - and her drawing would probably be ruined.
