A small vortex appears in the lab, and someone who looks remarkably like Brainley - save for lack of mustache - steps through. The vortex closes behind him.

Alternate Brainley: Hah, it worked! I've successfully crossed the barrier between parallel universes!

Dobbsey walks in.

Alternate Brainley: Hello! You'll never guess what I've just invented!

Dobbsey: A laser mustache trimmer?

Alternate Brainley: What? No! Well, actually, yes, but that was weeks ago!
