OK so my thought for Phillip, because how dare you present me with the opportunity to make him an actor- an 'illegal' child who was snatched up by the producers and is sent along with the actual winners for the dual purpose of essentially being a hype man and also to Keep An Eye On This Shit. Probably the first time he's been away from the producers for so long, so he could either wind up enforcing their rule as much as possible or going rogue on everyone's asses once he figures out that brainwashing is Bad. Basically my MO of 'full chaos/wildcard'.

ALTERNATIVELY he could be just blatantly there to help host, if that's something you guys need.
