Well, that was fun. Castle aired "Undead Again," the second to last episode of Season Four, this week and the outing consisted of breakthroughs, decisions and zombies. Let’s discuss.

Undead? This week’s case focused on an attack by a zombie. Going into this episode and having ready the description, I was a little hesitant. The idea seemed a little far fetched, even for Castle, but I was so wrong. The episode was light hearted and fun, just the way we like this series. 

I have to admit the blue eyes and some of the makeup freaked me out a bit. But serious kudos to the makeup department for making me question the reality of zombies, if only for a minute. Hey, Ryan did the same thing!

Did anyone notice that Gretta was played by Tiffany Dupont, formerly of Greek fame? It was good to see her back on TV!

Punishment. So Martha makes the point that Castle is trying to punish Beckett because he is pissed about her not acknowledging his “I Love You.” Have to say... I get it. You put yourself out there only to be rejected in a way that doesn’t seem like rejection. A way that makes it seem like it never happens. That is rough. As a full fledged Caskett fan, I want these two to move forward. I know all of you fans do too. But should Castle act like he is okay with it?

“When a life altering moment occurs, you remember.” The wall is coming down!! Beckett admits to Castle that she has been seeing a therapist, trying to work through the issues from the day she was shot. This was just in time, considering that Castle was thinking this may be his last case.

The issue has been debated since the beginning of this series. The two obviously have great chemistry. They make a great team. You can’t move too fast in a series or it will lose its spark. Is now the right time to move forward? Fight out in the comments, TV Fanatics.

After Thoughts:

• I totally want Castle’s laser tag game set. That was seriously awesome. 
• How can you not love Castle when he is sure that “the killer’s a zombie!” then high fives someone? Almost reminded me of another awesome prime time character. 
• The picture of Castle and Alexis in the apartment is adorable.
• Where was Lanie???? 
• Alexis decides to go to Columbia University. Looks like she will be back around for next season.
