It’s Christina Estrada and she’s at PAX East to sell WoW trading cards, or something. Not that you care. Not that anyone cares. It’s a cute girl in a Monk costume that won the costume contest at Blizzcon last year. Cosplay is about the visuals! You can always mute the video if need be, though I recommend against it since Christina is well-spoken and she talks about enduring the judging at last year’s Blizzcon, her other costume efforts, and what she’s working on for this year’s show.
Thanks to the indefatigable fmulder for the tip.
