ABC’s ‘Castle’ season 7, episode 21 review: A double-fakeout in the air

For the majority of Monday night’s new episode of “Castle,” we thought that we had a good idea as to where this story was going. After Castle and Alexis discovered that there was a murder on their trans-Atlantic flight to the UK, they had to do their part to figure out just who was the killer.

Over the course of the hour, it turned out that we had one accusation after another after another. The real fun came here in that by the time Castle and Alexis moved on from a possible terrorist (who was really just a student trying to see his sick mother), we thought that the next suspect, a woman with an ax to grind against the airline, was the culprit … at least for the most part.

The most unsurprising part of this case is that we knew that at some point, a flight attendant was probably going to be the guilty party. After all, it just made way too much sense. How else would someone have the access to seating charts and so many intricate details to pull this off? The murder was never intended, and this was all a heist that went array.

While Castle and Alexis were the anchors of the story (which was a nice change-up), Beckett still had a key role running point on the ground. Meanwhile, we also had some great opportunities to see Lanie implemented into the story, a nice reminder that Alexis studied under her.

So what did we learn over the course of this episode? Mostly that Alexis would be a great hostage negotiator, that Castle can tackle a case in the air with only limited outside help, and that these two still make quite the crime-fighting team. It was both unpredictable and predictable at the same time; even though we’ve seen many of these “plane episodes” of murder-mysteries before, “Castle” still did enough right to hold our interest for most of the hour, and leave us ultimately interested in more. Grade: B.
