As the greatest minds of our generation have said, time and time again: the first rule of fight club is that you do not talk about fight club, not even if you're Summer Glau.

But, luckily, I let my fight club membership lapse (I forgot to send the renewal slip in on time), so I am ready and able to talk my head off about "Kekoa (Warrior)."

A lively, nicely-paced episode, "Kekoa (Warrior)" stripped things down to basics - no high-tech weapons or elaborate conspiracies, just straight-up bad guys, people getting kicked in the face and someone hitting on Steve's mom.

Though it didn't quite provide the high-stakes drama of recent episodes like "Hookman" or "Hana I Wa'la (Scandal)," I thought the hour was very effective, in no small part due to Glau's turn as Maggie, the mourning daughter/ martial arts bad-ass.

I've been a fan of Glau's since her time on Firefly (yes, I write about TV on the Internet, so I am legally required to love Firefly; it's in the Constitution, look it up!), and I thought she turned what could have been a ho-hum part into something memorable with her formidable acting chops (as well as her formidable face-kicking chops).

Glau - who also did great work on the gone-too-soon Terminator: The Sarah Connor Chronicles - is always pretty excellent at combining expressiveness and depth with ass-kicking skills in her roles. She's a true gem for anyone who likes their action-adventure to be emotionally engaging, and I hope she finds her way to a regular TV gig again soon.

One of the consistent delights of Hawaii Five-0 has to be the guest stars - from Firefly's River Tam, to Freaks and Geeks' Bill Haverchuck, to Alex Mack herself, you never know which iconic star of cult TV or film is going to wander across the screen at any given moment. We can now add to this list Treat Williams, the man perhaps best known as "the dad from Everwood."

Williams charmed, wheedled and grabbed almost all of this week's best Hawaii Five-0 quotes as the private eye who mixes business with pleasure with Doris McGarrett (ah, but who among us could truly resist Christine Lahti's charms, right?).

The episode also included an important public service announcement: if you attend a rowdy bachelorette party that ends with the bride-to-be getting humped on by a guy in leather chaps , you will witness a murder within the next two hours, no ifs, ands, or buts (or butts) about it. Be careful out there, ladies!

Did you dig the mixed martial arts action? What did you think of Kamekona's brief flirtation with the wrong side of the law? Who's been your favorite "famous from another show" guest star so far?
