Here are some of the latest Chuck spoilers involving Summer Glau (next month’s guest star) and Sarah;
- The worlds of Chuck and Firefly will collide when Summer Glau guest stars as Greta next month. Casey and her will cross paths, there will be a mini-Firefly reunion. (by exec producer Josh Schwartz)
- The show is reportedly casting a pole-dancing class instructor. Since Ellie is pregnant and this seems like the sort of thing Sarah would need to learn for a new spy cover, it’s likely (but purely speculative!) that Sarah is the one headed to class. (E! Online)
