I can see it ending two ways :
with a TNJ and Dabi wanting to stop his massive explosion and Dabi wouldnt know how to stop his fire like when he was a child and Endy teaching Dabi how to stop his fire to atone for when he wasnโt here when Dabi burnt up
or
same TNJ etc but with Dabi impossibility of extinguish his flames and Endy sacrificing himself and carrying Dabi in the sky for the massive explosion to happen

But honestly, I think all this talk about how Dabi shouldn't be alive, his physical decay, and now a bomb just tells me Hori is going to have the Todoroki's save him somehow. The build up just feels like easy bait for the ultimate "save him" moment.
