"Hmm?" And then, it hits Strange. Oh shit. Something really weird did happen! His expression goes from confused to shocked to downright worried.

"Oh damn. You split in two! This...well obviously this is some sort of magic. Stand back, I want to examine this."

And Strange gets to his feet, not even bothering to put his shoes on. He gets some distance away from Rita then flips on his third eye. The burn scars on his hand, forearm, and forehead light themselves on fire as he stares at her, trying to examine the magic.
