Pine Barrens is one of my favorite episodes, definitely. It also has to be about the funniest.

As far as Tony's paranoia goes in "To Save Us All...", Pussy was definitely acting strange. The only problem was that it was 1995 and Pussy had only been a rat since 1998, according to the FBI.

So maybe Tony was indeed just being paranoid. But given Pussy's demeanor in "To Save Us All..." I've always thought it simply an inconsistency in the series.
