Just an observation:

When seated across from Andy, the Fireman holds up his right hand and makes a gesture identical to the Vulcan Salute as a way to conjure the box into Andy's hands.  

A similar gesture is made by TMFAP in FWWM when he sits across from Bob and administers the bone-chilling ritual above the convenience store. However, in that case, the fingers are split differently.

The similarity of the two gestures reminds me of the connection between the two: the drawing of the giant holding the dwarf's hand; the enigmatic "One and the same" comment  . . .

I believe the gesture appears somewhere else in the current series, but with the left hand. However, I can't recall just where.
