 *I agree this episode was weird....the kids is back but he left with his uncle two episodes ago, Rebecca and Simon were talking about a missed date that was never talked about before and all of a sudden Bobby had a hurt hand from a fight he had that was never in any other episode. I kept thinking I must have missed a show even though I knew I hadn't. Weird!  

  
 :I think, that they were supposed to do a double episode this particular day, but didn't, and something screwed up happened. To be honest, I came here looking for answers. -
