Just at home drinking coffee and flips a leaver on some machine that needed to be flipped to stop the reverse time paradox from moving the island and killing 12 year old Benjamin Linus who was actually a pretty cool guy.
A pretty cool guy who does not afraid of anything.
I can just imagine Patches showing up at the end of an episode:
Beedog- "Hey Patches, where have you been? You missed Man night!"
Patches- "Oh, I'm sorry. A strange man asked me to help him push this big button on the back of a robot."
Beedog- "Wait... That was you who turned off the Giant Evil Mecha-Dan?"
Patches- "Sorry, was I not supposed too?"
