The Whole Mind Collective, or WMC, is a group of activists fighting against Severance. Their goal is to end Severance. They believe that the severed employees are forced to undergo the procedure, and that it is tantamount to slavery.
Mark Scout confronts a group of WMC young people passing out flyers while on his first, disastrous date with Alexa. He becomes defensive and antagonistic but does not out himself to those activists as a severed worker, nor does he defend the practice, interestingly.
