Michael does came back in the fifth season. Itunes released the first four epodises. I already seen them. I don't know why they have released them so early, when the season hadn't started on tv yet. I'll give you a give away of the first one. Colonel Sheppard, Ronon, and Rodney finds Teyla and rescues her. Rodney delivered Teyla's baby on Michael's hive ship. I think they blow up the ship, after they escaped, but Michael escapes in their jumper, before the explosion. Colonel Sheppard and the others had to escapes in a dart instead. There you go, the first epodise is called Search and Rescue. If you have an ipod or iphone, you can buy them for 2.00 each.
