Think hard. The best episode of the entire series was...?
I know there are well over a hundred episodes..It's likely that most of us have not seen them all..but if you could only keep ONE episode and then the series would... I don't know.. fall into a black hole? Which one would it be??
I pick "The Refuge", the episode where a man stumbles to snowbound cabin and is told the world has been hit by a never ending winter. Everyone turns out to be frozen in sleep and Sanford Vallé is the only one aware of this and is controlling them all.
P.S. I would try to steal a copy of "The Haven" as well
