Cartwright won't be a playable character, he more of a helper. Grayson stays with the Maquis and the British Army until sometime in 1953 where he disappears during the Battle of Warsaw, so Insomniac will suck Grayson dry till that moment they've already started by having the Comics have him as a main character (The Comics were the decisive. They made Capelli and Grayson main characters which meant they are planning to go places with them.) they also mentioned Grayson being under SRPA contract in 1952 in Resistance 2 Co-op.
