Ther very first bit was so cute and so funny at the same time. The one liners both Beckett and Castle had cracked me up. When they were trying to figure out how they got there and you have the scene where they were in the house with the woman really freaked me out and I agreed with Castle when they found the 'instruments' that I thought it was gonna be 'saw style'. Brilliantly shot scene.
Finding the tiger scene was fabulous. Had some serious in there to balance out the funny. Worked really well in my opinion. When the tiger finally knocks the case over I thought one of them is gonna get seriously hurt here but it worked out in the end.
Feel for Esposito and Lanie. Really want it to work out for them. Gates again I liked in this ep. I swear my feelings on this woman change dramatically after every ep. Shows that Ryan and Esposito are good cops on their own.
Great episode, really enjoyed it.
