Ghost Whisperer 4/7 Lost in Space connection?

I only have watched 4 episodes. The pilot, the one with the mad bride

Capricorne...

and the last two episodes.

The guy with a hat and a mesh for his face? Who is he? Does anyone
remember an old Lost in Space episode? There was an episode where a
villian (trio) who had the identical wardrobe.

He was in the last two episodes of GW and wonder if the writers made him
to look like this as a homage to Lost in Space or is it pure
coincidence?

The last two episodes were far better then the previous two I saw and
looks like it has makings of being a continuing story and not
stand-alone episodes. I think the show has potential.
