Well, no one had given him a card yet. Seriously guys he might be a snappy Gryffindor who also happened to be a Leo which was the sign of a lion but he didn't bite you know? But it didn't surprise him THAT much that he hadn't gotten any cards so far.
That didn't stop him from making cards on his own though. So Kevin had grabbed a red crayon and an empty card before he began to doodle on it. Literally doodling on it since he only scratched some weird lines and circles on the paper before he added a text that was for his Prefect Lex. Since she was a Gemini.
When he was done with the card he checked it and then crumpled it up in to a ball. Spotting the Gryffindor Prefect walking towards the end of the room, Kevin stood up from his seat and
THREW the paper at her, aiming for her head.
