Go For It!
As I type there is a viewing of episode 3.13 Chuck vs The Other Guy happening at WonderCon. Spoilers are inevitable, and Twitter #wondercon is the place to find them.
If you have one and just can’t resist sharing, then this is the place. Of course, if you want to remain unspoiled for the next 26 hours (on the East Coast, anyway), then this is the place to avoid!
I also invite you to speculate as you wish right here.
Early Update: I’m not seeing spoilers yet, but the universal reaction is um… amazing! everything you could hope for from a bunch of rabid Chuck fans. I hear the SQUEEEEEs from here.
