Lennie James mentioned on Talking Dead how incredible of a worker John Carroll Lynch is. When they filmed the episode (which was shot out of sequence, James said they shot episodes 1-2-3-4-6-7-8 then 5 or something like that) it was during a stretch of hot weather that reached 106 or so a day, all while having to learn the lines of a episode in which his character (Lynch himself) would have to carry, not to mention he was learning aikido to make the role believable. Unreal.
Wish we could see more of Eastman but alas only in flash backs. The thought of having him conversations with Carol and Rick about the aikido's "all life is precious" .v. "die, die, die" philosophy of Rick/Carol would have made for some very interests scenes.
Still waiting to see Morgan and Michonne sparring.
