I think there's no way Mitch would've gone THIS week without the twist happening (especially on a Raul HOH) but tbh Mitch was starting to become a target anyway. He would've had to get in a lucky situation to go all the way. Probably would've been gone within a few weeks but I guess we'll never know now.
Also, another really good episode. Lots of little funny moments this episode (and in general lately).
