Mikey is just obnoxious loud liability that Toman and Sano family who they always Tunned out to even when he is serious about to talk about zombies. He just spamming zombies nonstop for weeks when the birds are gone and the air taste like blood & metalic, but no one cares as they don't even listen to him as he is an obnoxious loud liability who does not even know what he is doing anyway as he does not have y/n's notes on how to survive, y/n know how to survive while he doesn’t. Y/n knows that the Silence is the real warning, the second warning is the smell & the third is the power grid failing. They are still on the silence & smell phases so they have a lot of time before the power grid feeling that’s when the zombies will come. The rule might be don’t panic & be calm in the zombie apocalypse but y/n knew better as y/n know that real Rule is that silent is survival & noise is death as zombies are sound driven. Toman, Sano family and other gangs trust you more than mikey they quickly barricade the second floor, just destroy the elevator and the fire escape to blocking mikey trying to come up from the silent phase started before he screams about the metallic air and missing birds in the second phase.
