Sam had been, as always, sitting at his computer with a page of research spread out in front of him. The sound of someone banging at the door instantly caught his attention and he was quick to get up and head in that direction as soon as he heard that it was the Doctor and not some random person.
Pulling the door open, he couldn't help but let his mouth fall open a little in surprise as soon as he saw the blood ridden Time Lord slumped down before him. "Holy crap," he crouched down next to him and glanced over his shoulder, eyes scanning the room for anything that he could use to help the Doctor with his wounds.
"What happened? No, wait ---" He moved forward and tucked an arm around the Doctor's waist and started pulling him up into a standing position. "Come inside first. Sit down."
