Not to sound like I'm in support of this chicks ideas here but what if she is actually trying to help which from what I can tell seems to be an impossible task.
chris might be so far gone that her only way in was to RP?
also, she might just be as mental as Chris and maybe that's why shes fucking up an attempt at helping him?
this is just an incredibly optimistic assumption but I'm new here so what do I know.
Even if that's the goal, feeding into his delusions isn't going to help. Chris needs professional psychiatric help that he will never seek out.
