Well, Sam definitely had me fooled with his cover. And I was really looking forward to seeing how things played out between Ryan and Sullivan after Sam's attacking the latter, too. Damn you, CBS.
So does anybody have any favorite episodes that stand out from among the others for you?
My personal favorites are episodes 7 & 8 of season 4, "Into Hell" pts 1 & 2 (when Jonas' daughter was taken POW in Iraq and taken to Syria). Can't really say particularly why, but I enjoyed them the most out of the series. Maybe it's because I liked how their M4s were configured or something, I don't know.
Might seem like a dumb reason, but whatever.
