Dinah understood the need to keep moving. She had felt that herself. She deflated a bit when Dean mentioned that he had met the other Dean back in die Festung-at least, that's what she assumed he meant. Knowing that he had been there and might still be there now hurt, but continuing on and helping this Dean look for his Sam and keeping an eye out for her Dean was the only thing she could do right now.
She did, however, have one thought for the man who wasn't her boyfriend.
"You were stuck in that other world? You must be starving. We could grab a burger on the way to look for Sam? There's a place right around the corner that's your... your other self's favorite."
