Sarah and Chuck drive up to a McDreamy-style silver trailer in the middle of nowhere, at least for L.A. Chuck isn't sure they should do this, since she had to access an illegal database to find him. He clearly didn't want to be found. Sarah says it will be good to see him. They knock, but no one answers. So Sarah touches the back of Chuck's neck reassuringly, and they lean closer like they might kiss. Then the trailer door opens. Chuck: "Dad." The end.
The previews give everything away, so I'm not even going to say anything about them. I am not-so-silently protesting that the showrunners set up the episode so the dad would be a surprise, but then whoever puts the promo together totally ruined it.
