Good chapter, the fact that BJ is alive may hurt Dabi´s video a little, but considering that Endy will most likely accept the consequences of his actions, I can´t see him denying anything in a future press conference. Feeling pretty bad for the Todoroki´s family though, Endy deserves this, but they are in the middle of the crossfire.
as much as I like some depth into Dabi, that was really an attempt at a retcon towards Endeavour's character and trying to paint him in a better light.
It's really fine if he was a full time jerk father and going the vegeta route is better than creating flashbacks that mess with character consistency.
I might be a little too vocal but I do enjoy Endeavour as a character.
I mean, abusers getting worse over time is a thing. It seems that Endeavor got more abusive down the line, the change must have happened between him finding out that Toya wasn´t suited to be a hero and Shoto developing his quirk.
So far the Todoroki story is like this:
! -Endy realizes he can´t surpass All Might
-Endy uses his money to buy the approval of Rei´s family (wich is pretty damn creepy, so early Endeavor wasn´t a saint)
-Toya is born with a stronger fire quirk.
-Natsuo and Fuyumi are born.
-Shoto is born.
-Toya drawnback is revealed and Shoto´s quirk appears.
-Endy ignores Toya, also abuses Shoto and Rei.
-Rei snaps because of the abuse and is sent to the clinic.
-Toya kills himself in that mountain and Rei´s state worsens.
-Endy stays a piece of shit until All Might´s retirement.
The middle part may be missing some details that have yet to be shown (if Endy tried to force Toya to train after discovering his drawback or the order of some of the parts), but as long as Hori doesn´t try to make light of that abuse, then what we see in this chapter is fine, so at least for now I wouldn´t call it a retcon.
