The Killer (Whodunnit?)

The Killer is the main antagonist of the reality show, Whodunnit? Although he/she did not commit the crimes directly, most events happening around Rue Manor can be attributed to his/her work. As a fair-play game, we the audience don't know his/her identity until the reveal in finale.

Routines
The Killer usually starts a new day with a Rube Goldberg-style death trap set somewhere around the manor. When the poor victim is in sight, he/she unknowingly starts off a chain of events that eventually results in his/her demise. The next job for The Killer to do is to quietly pass the exam given after "stating the case", or if wanting to distract other contestants, he/she can earn him/herself a "Scared" card by pretending to fail the test, since he/she knows he'll/she'll be in the final 3 anyway. After that, he/she can sit tight in the dining room, waiting for Giles to deliver the name of his/her next victim.

Season 1
Main article: Cris Crotz The first season finale revealed the killer to be Cris all along. She "tanked Sheri, flamed Dontae out, blew Adrianna up, got Don mauled, let Ulysses bite the dust, drained Sasha and Dana, induced Geno's headache, blasted Ronnie, choked Melina and finally silenced Lindsey for good". However, at the end of season's finale, she got taken away into custody. And it's Kam who finally gave her the iconic golden cuffs.
