"Oh my," he says in response. And because he's all for helping while Doc inspects the frames, Dean keeps speaking. "Rule of three's. Wizard of Oz. Lions. Tigers. ...Bears. You live under a rock the last hundred years or are you strictly into books and text?"

Doc is busy - oh, with the mirror. Sure. He indicates that Dean she step back, or away, just in case. And maybe Dean reacted that way with the film, but he doesn't move when Doc tugs at the cover. Doc may see the writing first, but Dean sees the spirit - the shadow and he turns, suddenly. It's not behind them, it's just in the mirror.

"That is wrong."

Dean nods, though, not trusting the mirror now.

"Do you think that's here now and we can't see it or it's just in there?" he asks, crossing his arms, half circling the mirror and giving a long look around them.
