The cast was revealed 5 days after the cast was completed, which was on July 5th, 2020. In the event of the cast reveal happening, 1 houseguest walked and 2 were expelled.
==Twists & Changes==
*Have-Nots: Each week, four or less Have-Nots would be chosen by the HOH to live in a room with terrible conditions. They'd have to isolate themselves from the houseguests until the Head of Household ceremony at the session.
*Treasure Chest: Houseguests would go to the diary room & see if they could guess a 5 numbered code. Something was inside of it, & somebody got it on week 2 when people were allowed to guess on Discord. (code - 51407)
*Triple Eviction: On week 6 after stillrando's evition, people had to evict 2 more people in another eviction on week 6. It was a vote to save, & spartanfan808 got saved over Pokemon73LP & R_xyan in a 2-0-0 vote by ltsMo0se & ZachariahCarey.
