Warning: Spoiler Alert
I did get annoyed a bit with Castle on Alexis' behalf. Yes, he was trying to look after her, cuz he loves her and wants to protect her from all of the crazies and the ickies that are out there in the world. Still ... vlogging and blogging are how a great many people connect with their friends (as well as making new ones), especially when that someone is the age that Alexis is. And I'm not sure that he was giving her enough credit for being an extremely responsible kid, and I think that he may have been forgetting that she isn't going to be so silly as to put up something on her vlog that she would really regret putting up there later on. She's smart, and is probably going to be considering those things. It just seems like he has a tendency to over-react sometimes, and forget the fact that she is far more cautious about things than he is.
I would really love if they had Alexis a bit more on the show. She seemed to be on quite a bit more earlier on in the series, but the number of times that she's been in an episodes (and how much she's been in that episode) seems to have declined. But what with the character being off at college, it probably wouldn't seem right if she were around all the time. It kind of makes me wonder of Molly Quinn is also going to school in RL? Maybe.
The leader of the group that was protesting the "Girls Gone Crazy" organization got on my nerves, not cuz he was protesting something that he thought was wrong, but cuz he was making blanket and misinformed statements about people that were completely wrong ... and he didn't seem to be bothering to try and make sure that he wasn't talking directly out of his ass. I especially loved [/sarcasm] the part where he tried to tell Castle and Beckett that his daughter would ZOMG!! never do what they were trying to say that she did ... even though it was pretty clear that he actually had no idea of who his daughter was as a person. Seemed much more like he was the kind that was never actually "hands on" when it came to being a parent, but thought that he knew everything that there was to know about his children since he was their biological father and had only a vaguely passing knowledge of who they were. And it didn't help his credibility in my eyes that he was being such a jackass about the dude who was killed, when the guy was genuinely trying to change his life for the better. It seemed much more like papa bear thought that there was no way for anyone to be able to change for the better.
Esposito ... oh, Esposito. Not that I can blame him for his crank getting turned by someone who is kind of dangerous, cuz I can completely understand why that would be kind of hot to someone. But it really seems like he needs to get himself some action, cuz he's been chomping at the bit lately, and that is no lie. I would kind of love to see him and Lanie get back together, but at this point, I really don't see that happening. They can probably be friends now, but I don't think that they are going to be a couple again (I would love to be wrong about that, though). And I did enjoy how Ryan was teasing him about it. I seriously need to draw hearts on both of their faces.
