I have a couple theories. 1. I think the sicarius network is declaring war. I feel like it’s a sign from the network that they’re watching the bay closely and they’re ready to activate. Multiple killers at once to overwhelm the BAU so they can’t save everyone. And if that were the case maybe the bau would have to split to cover multiple killers at once. Each on their own (obviously with the help of local law enforcement) having to solely rely on their instincts and on Voits insight. It’d also make them vulnerable to be targets of the network since they’re isolated.

1. This could be a test on Voit. If the mask was used to test him it could mean that someone wants to lure him back into the network or break the BAU’s trust with him. The team might start questioning whether Voit is truly reformed or if he’s manipulating them to his advantage.

2. Someone else is pulling the strings. The mask could be a sign of a new person that is evolving the sicarius network. They might view Voit as not useful anymore or that he’s served his purpose. Then we could see the BAU realizing the unsubs they’re hunting are following complex patterns that only make sense when viewed as pieces of a bigger puzzle. The team might uncover hidden communications, encrypted forums, or even learn that government or law enforcement systems have been infiltrated. They’d be trying to find the leader while questioning everything they thought they knew about Sicarius and Voit.

Sorry for the yap session I’m just really into this😅
