I question that Alexis got a good edit this past episode. Her storyline emerged but it wasn't the under the radar, underdog storyline that Danni had. Instead, Alexis has emerged as a big threat who will be targetted once most of the guys are gone. You can bet that Amanda/Cirie will put a lot of pressure on Parvati to vote her out at Final 5 unless Alexis wins immunity. So either she is out fifth or makes Final 3 by winning the last 2 immunities. If anything, Natalie may outlast Alexis because she is still being ignored whereas the Alexis story arc has begun after both have been ignored for so long.

By the way, I believe that this list will be debunked this week because I'm pretty sure that the big blunder happens in the next episode and it doesn't play out according to Triple Anything's explanation at all.
