Damn. Hearing that confirmed just turns Strange's expression to a frown. This was happening again?! Someone he cares about is being held captive in a faerie realm again and there wasn't anything he could do to stop it from happening. The main difference was this time, at least, Strange knew it happened and had an inkling of a plan to get the person back.

"I think that I don't like you," Strange says, holding up a hand to stop Rita from talking before he continues. "But we both want Childermass back. You look like death warmed over, so I don't know how much help you'll be able to be, but honestly? I've a feeling I'll need all the help I can get."

It's a roundabout way of asking for an alliance. After all, the grand total of people Strange could count on to help in a crisis situation is...one teenager. He's grasping for straws here.
