"We just have to be careful," Meredith says, turning to look at him. With what he's said, it sounds absurdly simplistic even to her. There's too much here to be wary of and she doesn't know what she's doing other than trying to keep out of the way like she said. She's relying on him and on sheer dumb luck and only one of those has proven at all reliable. Until they pull through this, though, she can't let it get to her and give him one more thing to worry about. "I don't like this, Sean, not at all. But if it's what we have to do... I don't want you straining your throat more than you have to anyway."
