I'd really like to have Jeremy and Sigma meet, though I'm not quite sure how! Sigma trusted Phil with his life and Phil delivered, so maybe Sig can keep an eye out for the brainwashed Jeremy as a favour in his absence? Maybe Sigma can drop small hints he knows or talk about what he learned from Phil about the Pizzeria just to remind him of his identity.

Or we could go with something completely opposite. Sigma is a Gamemaker, so maybe he'd be put in a situation where he'd be expected to work the brainwashed soldiers into his war plans? Maybe he'd have to do that while keeping an eye out for him?

Just a few ideas! Whatever you would like. I'm totally cool with both negative and positive CR.
