Can't I give it more than 10 ? Tell me I can IMDb.

This episode was brilliant- absolutely brilliant. There was never a moment wasted- each scene made sense.

It was tensed, very emotional and scary to the most-I could hear my heart beating faster and faster. The performances all rocked especially Sean Astin took the show this time. He was brilliant and easily one of the most memorable character of the series.

My favorite episode of the entire season. Loved it!!
