I think a case could be made for any of the bottom three going home. I wanted it to be Ken just because of his attitude. I thought it would be Karen because her dress was shapeless. Justin's was ugly - but at least you could see the design work there.
When Tim saved Justin, I thought it was a save from the heart. I, too, think Justin is a sweetie and think Karen was the one who should have been eliminated. But, I don't see Justin as ending up in the top 5. If I were Tim, I would have kept the save for later, when the judges foolishly eliminate someone who does have a chance to make it to the end..
