Caroline squints at Coulson as he leaves the lab. Strangely enough, she's pretty sure he's telling the truth. And well, if the goal is to get Tony to work on a cure, now he has a competent helper without SHIELD having to go collect one. She flips her knife closed and slips it back into her pocket.

"Spy school?"
