The last chance doesn't make sense. If they wanted Michelle in, they should have just eliminated Patricia. Granted that Patricia got the short end of the stick in selecting her assistant, well that's how the game rolls. It's just the luck of the draw....boohoo! That being said, why they only brought back 5 assistants to choose from is unfair. Last time they brought back enough people that the last person picking get's to choose. If that was the case, I think Richard would have declined it if he didn't feel like coming back and working with Patricia (or Layana).
As for this last chance, I understand why Michelle was doing it. Because she didn't make the worst dress (Patricia did by far), she just didn't listen to her client. She made t-shirt and pants when it was specifically mentioned not to do so. She totally ignored the challenge. What they should have done is for Patricia and Michelle do another challenge right there and then to redo their garments and see what they can come up with in a span of 2 hours (like they did in the last All-Star season when the judges couldn't make up their minds who to put through to Fashion Week).
