Ok well there are clues for Firey everywhere now. The 2 digits that are revealed to the house now are clues:

The 1st Digit is 001. Just take away the 00s, and you're left with 1. 1 being that there is 1 person in the house that shouldn't be there.

The 2nd Digit is 013. take away the 0 again and you are left with 13. Which is the total number of houseguests that entered the house. And that is Firey's number.

Also in the upcomming HOH, the tie breaker has to do with Firey's number also.
(13:13)

I just hope Firey isn't evicted otherwise the twist won't go as planned.
