Most if my thoughts have already been covered by others, but the part I can't get over is Michael's shift in personality.

It seems like every time he talks now, I can't even recognize it as Michael Cross. He has become a pushover. He calls CJ on lying to Saul and Vic and she threatens retaliation like he is an AWOL soldier and Michael instantly crumbles.

Pegs goes in to her lets be friends speech and tells him he is fragile and weak, and he still leaves like all giddy with a big grin on his face. What happened to the Michael that took a shovel to a guys face for hurting one of his friends, or stood up to Marcus for lying to the colony or took charge in Irwin and rallied some troops to stand up to a superior officer and delay the nuke detonation or brought a zombie body back for testing even though he was ordered not to? What happened to that guy?
