Actually, I was tongue-tied during the whole Episode.
It was not just the jaw-dropping fight sequence, it was also the given background story of Endeavor linked to his family which made his character so much more interesting and complex. Thus his fight against High-End was Endeavor's most important one in his upcoming superhero career as the number 1.
All in all, my hero Academia finally delivers a superb last episode which strongly hypes for the fifth season, but also contributed by the sole post-credit scene. That one smacked my chest so hard, it turned into mere happiness.
