When the season started my gut said F2 and now is the only confirmed spoiler based on pre-merge boot interviews, the dates match up to F4 last episode. If there is a double boot episode or someone is evacuated we may have a recap episode this season.
based on this photo rumors have speculated F7 3 Brawn's 2 Brain's and 2 Beauty's so the person made their F7 boot speculation fit this criteria but the picture confirms nothing and was speculation to begin with.
