Last night, Mary Murphy kept Joshua and Chelsie on board the Hot Tamale Train.

But I’m guessing those two need to jump off now, if only because the show’s little locomotive needs to chug into the “Dance” station to bring two more contestants home.

And unless America has jumped on the Crazy Train, those two will be Mark and Comfort.

In my view, last night’s show pretty much confirmed three of the Final Four dancers: Will, Katee and Twitch. The last slot will probably go Chelsie. (Unless I’m mistaken, and the show lifts its weekly “one guy, one girl” elimination rule next week. If so, she’ll fight it out with Joshua.)

Will and Katee are, inarguably, the most technical dancers on the show. But can they match Twitch in charisma? Hard to say. But one thing is definite: Those three brought the best performances of the night.

First off, Nigel nailed it when he said Twitch and Katee delivered one of the most entertaining routines EVER on the show with their Mia Michaels contemporary number.

Just earlier this week, I was noting that this season hasn’t brought too many memorable moments so far, especially when compared with the Emmy nominated ones from last season. I stand corrected.

Because that kick-butt number totally rocked, from Katee’s Amy Winehouse-inspired beehive and eyeliner to Twitch’s laid-back sneer! I’d have liked Katee to get a bit more psycho ex-girlfriend, but other than that, these two were fan-freakin’-tastic.

How could you not love that one move, where Katee was hanging onto the door when Twitch slammed it? Brilliant. And that hot smooch at the beginning? Yeah, baby, yeah!

(And yes, Nigel, I would like to know what goes through Mia Michaels’ head. In fact, I’d like to take Mia and Mary Murphy out for a martini or five one night and see what flies out of their mouths. I’m guessing it would be the best night ever.)

As for Will, I was less in love with his routines with Courtney than the judges were. Their samba was fine, but that’s all, and frankly, I was expecting the judges to slam their slow hip-hop as being emotionless.

Maybe it just didn’t translate for the at-home audience, but I got nothing out of what was supposed to be an emotional number.

Looking at those pictures of her dead lover, Courtney could have been reminiscing about a fun night at the sorority house for all I knew: “You guys! Remember when Tiffany got so wasted, she barfed in Lauren’s hair and we couldn’t get it out? Good times…” She certainly wasn’t making me tear up over someone who’s passed away.

No, it was his solo where Will really stood out. Yes, some might have called it a schlocky James Brown impersonation, but it was still damn fun!

And that counts for a lot in a season where I’ve desperately wanted to hit the fast-forward button during all of the solos because they’re so boring and predictable. (For example: Comfort—same ol’ popping and locking—and Courtney—standard contemporary emotional/sexy head whips with one arm around the neck.)

As for the rest of the numbers, I didn’t really agree with the judges—including guest judge Toni “M-I-C-K-E-Y” Basil, WHEE!—on most of them. (P.S. It is me, or has Toni had so much work done that she looks like a complete alien life form?)

Except for that one wild airplane lift, I didn’t think Chelsie and Joshua did so well with disco; Joshua, in fact, looked like he was about to collapse halfway through, despite his “strength.” Their tango was pretty good, but not out of this world. And Katee and Twitch’s Sweet Georgia Brown was cute as a button, but I wouldn’t have called it terrific. (I thought Katee’s “rockin’ the boat” Broadway number with Will from the other week was far better.)

Then there was the hip-hop “detention” number by Mark and Comfort. Were the judges high?!? These two weren’t in sync at all, especially in the beginning. And it seemed like they had more desperation than joy in them, despite Toni Basil’s comments. Mark’s “stank face” looked just like he smelled something bad; he was completely anti-ghetto.

The judges must have woken up from their stupor, though, when these two sailed—or rather, sank—onstage for a fox trot. Nigel was being kind when he said they were “slightly amateurish.” Comfort’s never looked comfortable in genres like this, but Mark was truly a surprise disaster.

(And note to the wardrobe department, which is apparently obsessed with feather-covered costumes this season: Either find an anti-molting solution, or do away with the bird outfits.)

With that, does anyone think Comfort or Mark WON’T go home tonight? Mark’s as close as you can get to a sure thing, but Comfort’s always been a wild card. As she said last night, she’s a fighter.

Could Courtney be the one hitting the road?
