I loved the whole calling Castle "kitten", and when she appeard in Castle's book reading just to bother him at work and ended up mad at him for choosing the name Nikki Heat for the character. Also the poker game and when she told him about her mother. I loved all those times when Beckett was being "mean" to Castle

Love this scene with Lanie form the first episode

Kate: No signs of struggle. He knew her.
Lanie: Even bought her flowers. Who says romance is dead?
Kate: I do. Every Saturday night.
Lanie: A little lipstick wouldn't hurt

I feel like should put every quote and moment from Beckett in here because she's awesome and it's impossible to choose just a few ones :D

Well thats probably my fave word that she said to Castle, was she called Kitten, that was so sweet!!!!

I know there are so many quotes I like... I like the "lipstick" and "kitten" one!! I also like it when Castle was talking about marriage and she says... "I'm more of a one and done kind of girl". She's so cute - she's also a one writer girl! I like that about her!

Season 1 Episode 1: "Pilot"

Castle:It seems like I've got a fan.
Beckett:Ya a really deranged fan.
Castle:oh you don't look that deranged to me.
Beckett:What?
Castle:Hell Hath No Fury? Angry wickens out for blood? Only hard core Castle groupies read that one.

[I love the first episode, its such a line blast;)]

Season 1 Episode 7: "Home is Where the Heart Stops"

Esposito:Nice dress.
Beckett:I would let you borrow it Esposito but you stretched out the last one.

[Great Line!!!]

From the same episode:

Beckett:Oh so many layers to the Beckett onion however will you peel them all.

''KITTEN''
