Comment by REMY on Shotgun Boy - Chapter 42

@REMY  considering the trigger is one individual awakening the seed for evolution/transformation and we saw a massive outbreak, how did Zero spread it far and wide to induce a mass outbreak?

In Sweet Home, it’s probably a different cause because variants don’t exist in Sweet Home.

@Random commenter that's why it's the prequel 
It took place before Sweet Home
