With Chuck and Sarah on the run together without the watchful eye of the CIA, anything can happen on next week's Chuck. As we already saw the preview, it looks like things are going to get hot and heavy between the two.
In fact, according to Ausiello's latest spoiler column, the only thing holding back the two from having sex next week is a condom. Oh come on Chuck, every nerd learned in high school to carry one in his wallet (despite the fact that ruins them).
Ausiello also reminds us that there will be two weddings during the season finale. Series creator Josh Schwartz teases, "Chuck throws it for someone he cares about."
