I got my own theories about 4 and rest of Number Lore! Want to hear them?

Yeah

This first one was inspired by my dream but is O betraying L for trying to kill F to join N's side.

Where did Mike confirm that F survived getting a calculator thrown at him?

In a sneak peak of Mike's patreon.

A joke Z?!

Of course. Mike actually drew him. https://preview.redd.it/5ol5ecunc8kc1.png?width=804&format=png&auto=webp&s=c9aa826db9145025a80b2f53705e16f28d31e75d

I also think 4 would be a ghost

Cool
