"Psychological control?" It's clear Nadine's only offering it as a suggestion, something she's come to after a bit of thought. "I've read about a lot of psychological experiments and research, and it's a tactic used sometimes. Create a divide where there isn't one. Treat one group differently than the other, make sure both groups know...maybe they're hoping we'll spend more time being suspicious of each other than them."

Or they just want to keep everyone off balance and guessing, again, for control.

"There's all sorts of ways to show and exert control that don't obviously look like it."
