Halfway decent plot, but yet another stupid way to keep them apart.
Yea the plot was ok. But the whole have Castle go out with an 'invisible' airplane stewardess (iirc)... was just a lame plot device.
They're treading on some thin ice here when it comes down to the whole 'will they or won't they?' issue. Yea things are supposed to turn out ok in the end... but if the whole lame dialogue and lame ways to keep them apart continue on for much longer... I won't even bother to watch the show.
It's gotten to that point where it's almost not worth it anymore
