Speaking with Sports Illustrated, the NXT superstar reflected on being grateful for his fans’ support: “I’m extremely grateful for everyone’s support. I’ve been through so much. I started at the bottom, and now I’ve gone state to state, country to country.
I want to be there to support the people who support me, too. It’s so cool to see people care about what I do, and I hear them when they say they want more. I am grateful that so many people are invested in what I do inside of the ring and outside of the ring.
That’s something special about WWE–the platform, globally and locally. It’s really special, and I’m grateful for our fans. The reaction I got a couple weeks ago in Boston was amazing. I’ve worked so hard to grow my fan base, and it means the world that people care about me the way they do”.
