This week on Castle, we find out diamonds aren't always a girl's best friend when a priceless man-made gem gets a marriage therapist murdered. Meanwhile, Linus the lion causes Castle and Beckett to argue over which one is the dominate pack leader in their relationship.

Who's the Alpha?

Since Castle put a ring on it, some of the more Caskett-centric storylines have ended up on the backburner. This week, our favorite couple is back to the fore, as Beckett wants to make a tiny cosmetic change to Castle's sanctuary. 

Watching the back-and-forth between the two major partnerships on the show is always enjoyable, but the case-of-the-week is far more lackluster. Castle tends to do better when it uses the case to reflect an issue facing the characters or send up a pop culture genre. This episode is more of a standard murder mystery with some character stuff thrown in, and while enjoyable, the season has produced much stronger episodes. 

Coming down off last week's really strong case and the way it dealt with the relationship between Castle and Alexis, this one is a little bit of a letdown. The biggest character stakes this episode revolve around the photograph of a lion named Linus. 

While Castle initially stands up for poor, misunderstood Linus, the lion is eventually regulated to some other part of Casa de Castle. In his place is a collage of seashells picked up by the pair in the Hamptons, a nice romantic compromise. Although, possibly Linus isn't too pleased.

While Castle and Beckett fight over the fate of Linus (as well as Beckett's office elephants on parade, with their good family values), Ryan and Esposito fight over who the alpha is in their partnership. Espo clearly thinks he's top dog, since Ryan's by-the-book attitude and love of sweater vests can definitely undercut his toughness a bit. 

By the end of the episode, however, it seems like all the couples are on more even footing. Except for the Warners, who discover that while diamonds are forever, true love can be far more fleeting. Especially when murder is involved. 

Diamonds Are Forever

The murder of Alice Clark, a popular relationship expert to the rich and famous, manages to get Castle and Beckett to pause in their argument about a problem in the bedroom. That problem being Linus the lion, Castle's spirit animal who really freaks out Beckett. 

Alice's murder continues to get weirder and weirder the more they investigate. Some police work leads them to Barrett Hawke, a well-known "fixer" who is like Teflon for charges. With Hawke as a dead-end, they end up following Alice's client files to a hotel room she rented for herself. Inside, they find one of the biggest diamonds ever. Think "I'll never let go, Jack," Heart of the Ocean kind of big.

Most huge diamonds have a story behind them, but the tale told by Alice's diamond is an empty page. While Espo mulls over skipping the country with the rock and Ryan mulls over how badly he wants lunch, the two are attacked by a bunch of mask-wearing clowns. As if clowns needed to be scarier. 

Soon the mystery of the diamond deepens when it turns out the stone is actually man-made and flawless. This bumps the price up from $60 million to "priceless." 

Beckett finally gets the fixer to talk and he points them in the direction of the Warners, who paid him to get the diamond back from Alice. It turns out Alice and and her boyfriend mugged the rich couple to steal the diamond in order to utilize the technology to end conflict diamonds.

The only problem being that Mr. Warner had already sold his diamond-making technology to a diamond cartel, one that would be pretty unhappy if they were put out of business. Although all fingers point to Mr. Warner for the crime, it turns out it was his "not-so-better" half who actually killed Alice. 

Mrs. Warner wanted to scare her former therapist, but the gun went off and killed her instead. The Warners' diamond might be priceless, but the price of trying to protect their secret is definitely going to be some jail time.
