Cisco grabs onto Caitlin to try to help steady her and it takes him a second to realize what's wrong. It doesn't make sense, because they know Barry was just trapped in the Speedforce, but he's been okay. They've known that.

It's okay, you're okay. I'll explain, just...let's get you back to my room so we don't get caught talking about stuff that's not supposed to exist. Okay?"

But even as he's asking it, he's guiding her down the hall just the same as he had been guiding her away from the elevator. If he was in her shoes right now, it isn't even a question in his mind that she'd be doing the same for him. "I promise, it's okay. He doesn't have his speed, but he's okay."
