Chuck and Sarah's big wedding day is almost here, but they hit a major hiccup (OK, it's more like a roadblock) in this week's episode. Their relaxing day off quickly turns into a hunt to find Chuck's mother, and though everyone gets out unscathed, they set the wheels in motion for what becomes a huge cliffhanger. I couldn't help getting a little emotional at the end of the episode, which nicely sets up next week season finale. Once you've processed, see how well you were paying attention!
