Yeah, it's been pretty gnarly. It's fun. It can only be fun, unless you're really squirmy about that. Honestly, during that guts episode, they didn't tell Andrew and I anything. They just put trenchcoats on us and said, "All right, just stand right here and we're going to put this stuff on you."

Confidence. That's huge as an actor. Confidence can get you a long way. Maybe it's a cultural thing, being Korean, but my first reflex has always been to exude humility - but it doesn't help you in acting. For acting, humility isn't the best thing. It'll weaken your work. So it's a head game for me. "Can I really be confident in knowing my skill set is down? Can I perform like I own this role?"

There's no drama. There's nothing. Everyone is there to work, everyone is really kind and everyone is very helpful, especially to me. I went in there, hoping to learn. I could have easily been put on some project with somebody who really doesn't care about teaching or sharing. But, while I was there, all of the cast were very helpful. I would constantly ask questions.

I'm Korean-American. Not Colombian. My parents are first-generation, and I'm like... in-between, because I moved over here when I was four or five.

I took up boxing to get in shape for filming because it's grueling - all the running, the heat, the yelling, the crying that we do.

Whatever I lack in size and strength and speed, I kind of make up for in being grittier. When it comes to something like basketball I'm definitely not the best guy on the court, but I love elbowing and pushing people out or boxing them out.

Yeah, it's scary. During filming, it wasn't just jitters from being the newer guy there or the greenest guy there. It was also fear of not messing up such an important character.
