I have watched Jack with interest all season. Tonight he really seemed tired. I often wonder what they may give the dancers the day of the show to get them through the night. I know a lot of them are in pain and never show it. Yeah, I noticed Jack was a step behind Cheryl running up those stairs. I'm not sure he deserved a 10 but he is doing well. If this were last season Cher might be judging one night and then would perform the next. I would record the results show and fast forward through all her performance. I am surprised sometimes on So you think you can dance at some of the actors/actresses who are guest judges and some f them seem to have a lot of dance knowledge. But ballroom and Latin is different. I just may watch DWTS on the DVR next week so I can do some fast forwarding.
