Dean chuckled slightly at Seamus' proclamation of being a rockstar. Honestly if he was Dean would buy everything he made, but that was ridiculous. The drumming did actually look pretty cool though. The stick catching was even cooler though and his eyes widened in shock. He let out a little whoop of praise. "Niiice," he said, a grin of his own plastered across his face.
Seamus' compliment did things to Dean's insides. Those things were squishy and squirmy and made his heartbeat pick up in a slightly unfortunate manner. He wasn't sure why, Seamus had complimented his cooking plenty of times before. But to be compared to Seamus' mother? That was a very special sort of compliment. He covered up his attack of feelings by grabbing the brown sauce bottle and thrusting it at Seamus, with a "Thanks, man. Here," muttered in his direction. "I, er, made 'em from scratch," he admitted.
