You know I think Mordecai KNEW.
I think he knew when Carl, having forced his way into the safe room on the first floor only to hear 'those monsters chasing you will likely be back with backup'
Fucking TURNED AROUND
LEFT THE SAFEROOM
AND MADE SURE THERE WERE NO SURVIVORS
Before coming back to have his little 'ZOMG wtf' freakout and also feed his ex girlfriend's cat.
Like Mordecai knew THEN that he was dealing with a batshit crazy multifloor survivor. He just didn't let himself fully believe it until floor 3.
