i have finished the grim jetters questline and decided to do the ruins in black sea. i didnt do crimson meadow but i did do lemurian health center , nexus and then joint security (in that order) . when i went back to captain grim for my reward i left the boat and just spammed click on cruzer to see if he had something to say. accidentally i clicked on the deucer next to him and he said
"So ye been to an ancient deep sea station while i did nuthin' but sit 'ere?"
which sounds like something he should say after i have been to the abyssal station. Also it wasnt a bubble above his head like generic dialogue but instead it was actual dialogue where i had to press continue and end conversation.
