#10 Week 1 contestants are back

I was surprised to see them, but also glad. I was almost sure they'd had their chance (and their second chance). After all, Bob and Jillian brought Aaron and Elizabeth back and that could have been the end of it. Instead, one more person (Anna) was given a spot on the ranch, while Corey, Montina, Shanna, and Sandy are thrice devastated.
