After watching that episode at least 5 times, I've finally gathered all my thoughts.
I had almost no dislikes in this episode. I am willing to put aside any questions of logic, for as Rick once said to Kate "why are you ruining my story with your logic?".
So here are my favorite lines, broken down by character:
Martha (to Rick) - It's a spa trip, not a guilt trip.
Ryan
(to Kate) Staring at the phone won't make it ring. I learned that in junior high.
(to Castle) You've gone "Rear Window"
Espo
(to Kate, about Rick) How is Jimmy Stewart?
(to Castle, after Gates yelled at him & Kate) How hard is it to balance on the crutches when you've had your (butt) chewed off?
Kate -
(to Espo & Ryan) Unless the body you're looking at is dead, I suggest you put down those binoculars.
(to Rick, after suggesting she go across the street) Look at me. He's going to let me in
(to Espo, after his crazy answer about why men are such babies) Where did you read that? In "You're Making it Up" magazine?
(to Rick) Your overactive imagination is one of the things I love about you (and my reaction: wait a minute, "one" of the things!!!!!)
Rick
(while watching the couple) Oh to be young & underemployed
(to Kate) You do it, it's an illegal search. I do it, it's just illegal
(to Alexis) You get caught, you get a B&E on your record, you can't be President
(after seeing Kate all dressed up) Happy birthday to me
Some more observations:
loved Kate stinking out her tongue at Rick when she's knocking at the door across the street.
A few movie references I caught:
while playing with the helicopter, Rick mentions "Zero Dark Thirty". He also mentions "Red Five", which is Luke Skywalker's code name during the battle in Star Wars & Empire Strikes Back.
Also, caught another old episode connection. Alexis mentions how Rick thought her art teacher was a serial killer because he looked like someone on America's Most Wanted. On "Almost Famous" the victim, a would be actor, appeared on a similar show, and they thought it may have lead to his murder.
And I agree with the 3 x 13 reference. Not only is that their first kiss, it's about her mom's murder. Not so sure about 3 x 19 stuff. While I agree that it's a nice comment about their similar interests, overall that episode isn't that memorable.
