Excerpt from "Ask Ausiello: Spoilers on 'Glee,' 'Chuck, 'Grey's,' 'Smallville,' and more!"
Question: I have a Chuck query. I was wondering if anyone else will be finding out about Chuck’s secret in the near future? —Jenny
Ausiello: If by near future you mean this season then yes, someone else will be finding out about Chuck’s secret in the near future. In fact, this unnamed individual will not only uncover the truth about Chuck’s other life, he/she will end up joining him on a mission. And if you saw Monday’s immensely entertaining and hugely pivotal episode, you know it can really only be one of two people.
