Their pal Frank’s hard drive had been taken by big bad Leviathan Dick Roman, and he had a geeky IT girl hacking her way into it. And if she cracked the encryption and got that hard drive info for Roman — deliciously played this episode by James Patrick Stuart — he’d have all the information he needed about the Winchester boys’ aliases, where they have their car hid, and basically whatever he needed to find them.

Of course, one would think an ancient creature from the Bible probably would be able to find that info, anyway. But let’s not strain our brains too much, shall we? Just enjoy the creepy monsters and cute boys.

This hacker the Winchesters were dealing with was not so much “dragon” tattoo but more “Dungeons & Dragons” tattoo, hence the name of the episode. Or, to be more precise, Princess Leia tattoo, if you know what I mean. Which is to say, the kind of chick you meet at Comic-Con.

If you’ve ever been to Comic-Con you understand what I’m saying. If not, watch this episode and you’ll understand.

Anyway, our hacker Charlie Bradbury (Felicia Day) found herself with an assignment from head honcho Roman to crack this hard drive, even though she’d tried to blend in as a simple office worker bee. The problem for Roman was, once Charlie saw what’s in that hard drive, which was all about how he’s a Leviathan and wants to use humans for food amongst other things, it wasn’t too hard for Dean and Sam to sway her to their side.

Not only did the boys want her to delete that info on the hard drive, but they wanted her to sneak into Roman’s office to access his e-mails. And this poor girl ain’t no Angelina Jolie-type spy chick. So they figured they’d hook her up with an earpiece so Dean could talk her through everything.

That included how to flirt her way past a security guard they weren’t expecting. Now we all know Dean is the master of flirting, albeit usually with girls, not for them, but Charlie had another dilemma with this particular task — the guard wasn’t her type. Really not her type, being … male.

Now, you know that’s not going to go smoothly, right?

Charlie bumbled her way past the security guard into the office to start stealing data from Roman’s computer. She succeeded, got out of the office back to her desk, but guess who showed up just as she was trying to leave? Yep, Dick Roman himself.

In this episode, Roman went from being your garden-variety brand of evil to being delightfully psychotic — Stuart played him as strange cross between Donald Trump and Patrick Bateman from “American Psycho.”

Which is to say … awesome!

And it’s a good thing Roman has come along as one of the more interesting adversaries they’ve had in quite some time, as the series has been struggling a bit since the whole Lucifer and Michael storyline the first five seasons came to a conclusion.

Plus it was tough seeing Bobby go — well, sort of go. Having him come back as a ghost just doesn’t work and it seems a shame to bring him back like this when he had such a spectacularly written send off. That’s kind of cheating.

Next thing you know, they’ll be bringing Cass back. (Cough.)

But anyway, we need more Roman and I think I can speak for a lot of people — namely people with estrogen — when I say we need him in tuxedos more often. I think a lot of us were kind of feeling that, or as Dick Roman would say, that was kind of completing us. But then, most of us Comic-Con kinda chicks have a soft spot for a good-looking monster.

Blame it on Christopher Lee.

Anyway, they got the hard drive erased, they checked the e-mails, they intercepted a package for Roman although they still weren’t sure what they had other than a big block of clay, but in the end, our hacker friend Charlie saved the day. Unfortunately, she then rode off into the sunset on a bus.

She’s kind of a fun character. Dear writers, you might want to consider bringing her back in the future. Just an opinion.
