Two Fixtures, one Circuit. How does this work?
UPDATE:  As it happens, I finalized realized I had disconnected wires in a junction box in an adjacent closet months prior to noticing what I thought was a dead fan switch (enough time had passed that I didn't link the junction box to the switch).  Reconnecting the wires in the junction box solved the problem and allowed the previously useless romex bundle to now have a function (the romex is basically an extension to the switch box).  Thanks for all the help.
