Come on, Kids! Sign up for camp! Your minds are very important to us!
I have a headcanon that Oleander was caretaker of Whispering Rock long before Ford’s dismissal, and that it was his idea to move Ford there when his mind was disjointed. Sasha and Milla were Ford’s most trusted agents, so they entered cahoots with Oleander and together, the three of them run the summer camp. The current administration trusts Oleander’s ability to oversee Ford (who they think is crazy), and he’s the one who runs a smokescreen for Ford’s assignments so Sasha and Milla don’t get in trouble when they take down bad guys.
