i'd pm to see if they were interested in even threading with a close castmate. i've been in the position where i was a lcw with zero interest in castmate cr and someone apped in expecting to be prioritized. a simple pm would've saved them the disappointment of a castmate who didn't want to play with their character and myself the trouble of awkwardly opting out of the CR.

ftr, i'm fine with co-existing with castmates in games. i'm just more interested in exploring crosscanon options.
