Sam had already been up for about an hour when the note was slipped under his door. He'd slept from 1am til 5am, and although he had still been woken by the nightmare of his brother, four hours was a new record for him. He went out for a run around town when he woke to clear his head and then had gone back to the Sleepy Hollow to shower before heading to Jamie's apartment block to make an early start. He was glad that had been his plan when he read the note as he was now going to have to fit this 'pizza investigation' around repair work he was doing.
He left for work just after 06:15 and was there until 11am when he decided to head out for a supply run, a few tools and materials nothing major, which he'd overlap into his lunch break. Should give him enough time to join the Doctor and his team, get his supplies and he'd be back to his repairs by early afternoon. Assuming that they didn't find anything suspicious, that is, which knowing Sam's lunch they would.
He headed back from the apartments toward the Sleepy Hollow , catching sight of the Doctor and a redhead he knew to be Amy standing outside. Making his way over to them he instinctively felt the pockets of his jacket, checking for the familiar feeling of the weapons concealed beneath. It was a simple thing but something he always did before he ran head first into trouble, or at least the prospect of trouble. "Uh hi." He said as he drew up next to them, a little unsure how you exchanged pleasantries under these circumstances. "I'm Sam, we sort of met." He offered the introduction and a small smile to both of them.
