With all due respect... what were you thinking, hiding your anemia from the Doctor? It's not exactly conducive to the traveling lifestyle. As has just been proven by you. Because you just fainted on him. You really should've told him, you knucklehead.
However, you didn't, so here you are, in an alcove of an alien spaceship, laid out in the Doctor's lap as he checks your pulse. Daleks are screaming 'EXTERMINATE!' on the other side of the ship, and the Doctor is rather lost on what to do.
As you came to, he sighed with relief and pressed his hand against the back of your cheek to check if you're warm. After a moment, he decided that you were roughly the right temperature for a human and pulled his hand away again.
"Are you okay?" the Doctor asked, pushing and pulling you into a sitting position against the wall. "What happened out there? Are you dizzy? Fatigued? Have you been eating and sleeping enough?"
