Concept: Each poster gives three things Criminal Case based (suspects, locations, cases, etc.) and the next poster must name which one doesn't belong and why (there might be more than one reason, but it's advisable not to go for the most obvious reasons unless you're absolutely stumped).
Poster 1: Rupert Winchester, Yann Toussaint, Gabriel Herrera
Poster 2: Gabriel doesn't belong; he's the only team member of the three not to work in forensics. [new list of 3]
To start off: Cora Bateman, Kelly Purcell, Scott Morris
Dr. Mortimer Pickering. He's the only one connected to DreamLife who is not an accomplice to a murder (Ernesto was partly responsible for the multiple test subjects' deaths, and Herman was an accomplice in Wendy Stokes' murder).
Doris Black, Cora Bateman, Vicky Lopez. Two differences in the odd one out.
