So, by my calculations...
Case 1-Vic-Killer
Case 2-Vic-Killer
Case 3-Vic-Vic-Killer
Case 4-Vic-Killer
Case 5-Vic-Killer?
Case 6-Mastermind reveal, survivor escape (If it's not case 5)
Now if the killing game goes like that..
After C1-11 remain
After C2-9 remain
After C3-6 remain
After C4-4 remain
After C5-The 3 survivors escape
I do assume, that do to there only being 13 competitors, that this will be how it'll go
