We live in a bubble sometimes, and you can get out of touch with your fans. You go to the studio, you come home. But coming to Comic-Con is a real opportunity to connect with the people that made your show happen and are responsible for its continued success. It's really humbling.

I like to work as much as I can, but I only really have the hiatus to work on other projects. I've kept myself busy recently. I voiced a character in 'Ice Age 4,' which was a lot of fun. I also did another small movie called 'The Scribbler.'

When you move from a different country, it takes a while to make friends. I found myself being lonely a lot at first. In New Delhi, I had all my family. But Portland is one of those cities you can immerse yourself in and feel comfortable. People are so friendly.

I'm helping launch the new Milky Way Chocolate Ice Cream Bar. I play an astrophysicist on television, and the name of the bar is Milky Way, so put two and two together, and here I am.

I was pretty awkward when I was young, but I was never afraid of putting myself out there. I would say stupid things but then they would laugh at me and possibly find it endearing.

I have a fear of heights and I'm claustrophobic.

If you want to go on the floor, go in disguise because otherwise you won't be able to. I would just put on a full Darth Vader costume and walk through Comic-Con so I can actually check it out and enjoy it as opposed to being approached by everyone, which is lovely, but it gets very difficult to enjoy because there's so many people there.
