So FINALLY we get to see the Captain !!!!
Normally I am not really interested in the case, more in the Castle-Beckett scenes and Castle-Martha-Alexis scenes but this one really caught my attention :) Even if it was kind of twisted I found out who the killer was the second I saw Layla's brother, however it still was an excellent episode we some Casckett-y goodness at the end, I can't believe Beckett is a Sci-Fi lover :D
I also love to see daddy Castle even if his reaction ( tracking Alexis' phone) was definetely excessive ! Still the last scene between the father and the daughter was awesomely cute and I hope we will get some more Molly Quinn in the next episodes.
