I was wondering the same thing. If it was a manga chapter i'd say "flashback in 3..2..1..." but since the anime moves much faster i doubt we will see a flashback showing why.Why did he teach Darui how to use black lightning and not his son?
xdBecause A's just not black enough?
We don't know for now.
