Jon gushing (to use his own words) over Donkey Kong '94, talking about why he finds the game to be underrated nowadays, how it introduced lots of iconic things into the Mario universe, and how he found it so amazing as a kid.
His commentary during the credits, where he thanks his audience for enjoying the game with him.
Jon returns to one final Mario Romhack despite him officially having ended them years ago, "Notte Luminosa"; his reason for doing so? It's the last wish of the mod maker, who's dying of leukemia.
It was later revealed that the creator actually lied about the leukemia, but it was still a nice gesture on Jon's part, and he still had links to donations for people who are actually dying of cancer.
Better still: When Yanama posted a video on YouTube regarding the incident and where his head was at the time, Jon personally congratulated him for it:
I'm glad to hear you're getting help and that you're aware of everything that happened. More than anything, I hope that you use this situation to better yourself and become a stronger person, and by the fact that you did this video, it shows you're already on your way.
One for the fans, they flooded ScrewAttack's Twitch Channel chat with overwhelming support for Jon in the Iron Man Of Gaming competition.
