Lucie had heard commotion coming from the other room. And to be honest, she recognized the Doctor's yell. Sadly she'd heard it so many times, she knew when it was her Doctor and not the other one. That's when she raced inside and found the Doctor on the floor, and someone who looked like Tyler but wasn't Tyler bent over him.
"Oi," she grumbled, pushing her way past the vampires and bent down. "What are you doing?!" she so didn't get the whole blood thing. "He's a Time Lord!" Clearly he wasn't waking up, so she only did the next best thing that she could, and that was lean down, and try to scoop him up so that she could drag him to the Zero Room.
"Come on slow-poke, don't just stand there. Help me get him in the.. just.. follow me, all right?" No time for arguing.
