Shaken by what she has learned, Beckett tearfully seeks comfort from Lanie. The evidence suggests that Castle started the affair not long after she and Castle got together, but tried to break it off. The evidence overwhelmingly suggests that Castle is guilty, but after revealing how painful it was to watch him be arrested ("He looked like a little boy, he was so scared..."), Beckett once again affirms that she does not believe Castle responsible for any of this: "I know him, Lanie. He is an immature, egotistical, self-centered jackass sometimes. But he's not this."
Before Lanie can respond, there is a knock on Kate's door.
Kate slowly gets up from the couch trying to get herself together. Without even looking in the peep hole she opens her door to discover Alexis on the other side.
"Alexis, what are you doing here?"
"I'm here to talk to you about my dad"
"Alexis this really is not the time"
"Kate, no this is the time, you owe me that much. You cannot give up on my dad. He is not a killer and you know that. He loves you Kate, more than I've ever seen him love someone before. He would not just throw it all away"
"Alexis, you really need to just go home, right now. I cannot do this right now. Your dad has a history of being with multiple women. To be honest, I'm not surprised this happened, I was hoping he had changed and he wouldn't hurt me like this"
Alexis sighing forces her way into Kate's apartment, seeing Lanie on the couch. Alexis stands there for a moment, and tries to calm herself down. But she is furious, that Kate could even believe that her dad would do this. She turns to Kate and can't help but start yelling.
"KATE, you have no idea what you are talking about! This is not my dad. You do not get it do you? Four years he's been shadowing you and you still just do not get it! What the hell is wrong with you are you blind or just stupid?!"
"Alexis, that is uncalled for. I thought I knew your dad."
"Kate, you do know him, better than anyone, at least I thought you did. LISTEN TO ME BECKETT"
Kate can't believe that Alexis is in her home, acting like nothing is wrong and that she is to blame.
"Alexis," - Interrupting Kate. "No, you're going to listen to me then I will leave and if you still don't believe in my dad, then walking out that door will be a goodbye from my family"
"My dad is anything but a cheater. That whole playboy persona you met all those years ago, was a wall he built to protect himself from getting hurt again. First, Kyra, then my mom, then Gina. Kate, why do you think my parents are not together anymore? My dad doesn't cheat, he's the one that gets cheated on."
Kate gasps, she never knew that. She just thought being around her changed him.
"Once he started to really get to know you Kate, the wall came down and he started to care about you, he started to fall in love with you. Despite everything, he waited for you, he stood by and watched you date other guys in front of him. Even with you being someone else, he tried to take a bullet for you, in front of me! I've never seen him look like that. Then in the hospital, Josh attacked him blaming him for you getting shot, and my dad lost it, he just broke down and sat with my grams. All I heard from him before he started crying was, I told her how I felt."
Kate starts crying again at this point and sits down.
"Did you know after you were shot, and I watched him try to die for you, that I pleaded with him to walk away from you, that he was not a cop and that he needed to grow up. He told me couldn't, that he needed to be there for you. I asked him if you made him happy, he said yeah, and that it was enough for now. Kate you cannot doubt my dad, I cannot lose him again, I finally got my dad back. I never liked that side of him."
"Kate, he was ready to walk from his writing, when you came to that book party. It was he killed off Derrick Storm, he was bored with his life. Despite all the women, my dad was lonely. Then you walked through the door and something woke up inside of him." Alexis starts crying at this point. "Please do not give up on him, he loves you and he would not just throw that away. At least think consider this, you know damn well how much my father loves me, do you really think he would kill someone, knowing I would lose the other real parent I have left? If you can believe at least that much, go talk to him as his girlfriend, not as a cop. He deserves that much, even if your there to end everything"
Kate sits in silence for a moment trying to collect her thoughts and think about everything Alexis just said. She did not know Alexis was the type to do this kind of thing. She was always such a mature, laid back young lady and here she was pleading with her to believe in her dad. That he would never hurt her or Alexis. In that moment she believes everything Alexis just said.
Alexis sees something change in Kate's eyes and she hopes it's a good sign. Then Kate speaks,
"Alexis, I'm sorry, your right, this is not your father and I'm going to prove it. I won't it end like this. There has to be something else going on here and I'm going to go figure it out, but first I'm going to go talk to your dad. Thank you, Alexis"
Alexis smiles and hugs Kate who is surprised for a moment but then returns the hug.
As Alexis hugs Kate, she whispers "I knew you would see the truth. It's why I love you too" and with Alexis says goodbye and walks out the door. Leaving a shocked Kate standing there.
