Pretty OK episode of the gang re-enacting why the pub should be a landmark. Anything that had to do with a gun or Dee being a witch was pretty funny. Even in the days of the American Revolution, Mac finds something sleeveless to wear.
'Reynolds' was one of the names on the Monster's cave wall, so I'd guess that the Island-world of Reynolds was on the Island at one point or another in his life. Maybe he's there right now as an Other or was one of the dead Oceanic 815 passengers.
