To any spanish speakers: Dom gives this entire interview in kayfabe. Granted, the interviewer, Molusco, who is a dick and has a controversial reputation in PR, did a good job of letting Dom speak, elaborate his character, his motives and his role in the JD. There's a lot of nuance in his heel work here. He establishes that his allegiance to the JD comes from the validation they give him, the same validation that his dad didn't give him.
There's a fantastic heel moment around 3/4 of the way where Dom talks about when he first learned to run the ropes; here's an abridged translation:
D: "the first time I ever ran the ropes, my dad told me to run for five minutes. 15 seconds in, my back was already bruised and I complained. He just responded: "sorry" and told me to keep going. Five minutes later, my back is completely purple"
M: "It's Rey asserting his dominance over you. Like, 'hey I'm Rey F'n Mysterio and I've been running these ropes for 30+ years so this is what I feel on the daily'."
D: "Exactly. He told me he cried the first time he did this exercise. My uncle, Rey Misterio, Sr. who is also his uncle, told him 'if you're gonna cry, go cry in the corner because wrestlers don't cry' so he cried, wiped away his tears, and kept going.
Of course, I didn't cry because I'm a real man."
In one fell swoop Dom puts his dad over, gathers sympathy for him and heels it up.
For any completionists out there, Molusco also interviewed Damian Priest yesterday out of kayfabe and Chicky Starr last week. He is a respectful, although casual interviewer.
