"This isn't the House. Where is this? And where's my thief? I just found him - will find him? - but he always runs off." She sounds mostly exasperated about this, but there's a frantic concern underlying it. The only reason she isn't properly panicking about her current state is the fact that she can't grasp that thought any better than anything else right now. But she knows one thing for sure; if she can just find the Doctor, he'll sort everything out.
