In Episode 62, when William asked Sera who was stronger, what if John had arrived home a few minutes later? How would this change the story?

The story is set in the city of Atlantis as depicted by TheAtlanticCraft. Characters in it are either from the youtuber's roleplay series or the youtuber's discord. The main character is Jimena and it is written in a third person view. WARNING: It's zombies, so expect blood and gore. (Duh)
