I've been thinking of the Church 12-hours-of-planting-simulation that Avery had and wondered of what could've happened in the real world.
Everything goes as canon in DAWTDE, until the confrontation of Avery with Derek in front of the KiY.
Derek's plan to drag the KiY into his body so Avery could get out of here intact and getting mad at him because they'll both die if they stay. Derek already knows how things would be after his death
What he took for granted, was Avery's current IRL health.
Thing is, Avery has delicate lungs, growing up he was deteriorating little by little until something like a normal flu could potentially kill him. So, every time he was drowning in game in the lake at the church, he was kinda drowning too IRL.
Avery is in a coma and even if Derek defeats the king, the damage is done, he would die after everything is done.
The King planned this all along, after all, a vessel needs to be with a clear mind and a clear body (without a soul). It's a crushing revelation, since all what Derek wanted was to save Avery from that cruel king.
1. Bad ending, Derek realizes of Avery's health after pushing him into the void to save him from becoming a vessel, the server is now closed, and Derek is too shocked to even type anything since all he can see now was Avery's body shutting down. Derek dies not long after that.
1.1 terrible awful ending: Derek survives the fusion with the King, and now he has to live with the reality of Avery being dead instead of him. So yeah, let him mourn what he was trying so hard to protect, not realizing that he chocked with his hands and idk, probably living for eternity IG.
Both jump to the void and get isekaid to a realistic minecraft with the characteristics of their minecraft skins and species. The king is gone and so is their way out. The rest is them trying to figure out how to live with their new abilities and characteristics for however long they can, they have all the time in the world after all.
In real life, their bodies are found by their families/friends and are buried (or cremated idk) not long after that. Probably they became an urban legend for the minecraft community.
Like ending 2, they jump to the void and get isekaid. HOWEVER, the kind is somewhere around and they have the mission to find him in order to get back into the real world again.
In here, their families/friends found them just in the nick of time to leave then in a medical induced coma while their bodies and mind (plus souls) are healed.
Probably, like in the ending 2, they have to learn about their new bodies and have the adventure of a lifetime.
They end up alive at the end and meeting each other in physical therapy.
