Someone said it already but Danny Way's ashes moment was pretty intense. Especially if you've lost close ones.
Also, it's emotional but I like to watch it to get me hyped and push myself is Cardiel's epicly later'd.
To see a guy still push himself after such an accident is pretty inspirational.
Mariano and Marc in Fully Flared also play on my emotions but I think that's just the music and editing.
