I still agree with Tdalton that after what Chuck and Sarah went through on the season 2 finale, their feelings seemed to change too quickly to be real. I think it will turn out they they are just trying to hide those feelings from themselves but they are still in love with each other.
I don't think that this is a realistic direction for
Chuck to go anymore. Unless they pull a complete 180, tell the viewers that the last few episodes never happened, and then jump into a time machine, I'm going to consider Chuck and Sarah officially over. There is no way that they can realistically get them back together at this point. I think that, for the health of the series, they should leave them apart for at least the rest of the season and then hope that they're somehow granted a fourth season (which I now don't think will happen). Last night's episode was such a debacle on many fronts that I'm not sure that the series can recover in order to secure a fourth season. Now, it just seems like it's the march to the series finale on May 24th.
At least they already have an episode that could serve as a very good series finale, but one would have to go all the way back to Season 2 to find it. "Chuck vs. the Colonel" (the second to last episode of Season 2) will now be the episode that I end my
Chuck viewing with from now on, serving as something of an unofficial series finale in my mind (it actually wraps things up in a somewhat reasonable manner, unlike the mess that has followed in Season 3).
