I didn't think Emmett was being serious, and I don't think Talla was offended enough (or even at all) to desert Emmett. At the end of the show you could see Emmett and Talla talking and I think she knew what was up. Also, isn't Talla with Andrew? I don't think it would have been that easy to get a majority, or win the right comps. Still, Emmett, Jillian, and Andrew is still a superior combination IMO. They can win the competitions more than Peter, Topaz, and Talla.
