"You fucking bastard! This is your fault," John growled because he wasn't used to dealing with problems with fear, he usually just got angry. He couldn't blame the Doctor, it wasn't his fault completely and he was trying to help. John wiped the blood from his nose and closed his eyes for a few moments, gripping onto the Doctor so he could walk a little quicker. What the hell was this? Why did -- oh shit, that bloody thing that coughed on him.

John pulled a face, looking at the Doctor and trying to read what he thought because if the Doctor looked grim, it was likely he was fucked. "Cure, you got a cure! Right? Use it! Fuck, I-I can't die because of this," John sneered as he tired to focus his eyes, stumbling when he missed his step and nearly sinking down because it was really hard to focus right now. "Could you just stop the TARDIS for a moment, it's making me dizzy."
