Guest Stars

For her 21st birthday Claudia rocked out with the one and only Cherrie Curie. How bad ass is that?

Jane Lattimer introduces an artifact that will allow Claudia and Jinks to enter Artie's subconscious in order to find out why he won't revive, but when they get there, it's a tricked-out, electrified version of the Warehouse, complete with guardians in the form of Vanessa, Mrs. Frederic, and MacPherson.

Myka and Pete visit Professor Sutton, the foremost scholar on a 16th Century count who was said to bring flowers back to life. They hope to find an artifact connected to the count, one that they can use to revive the blue orchid and suck the illness out of the world, but the professor's no help - he's been hitting the sauce pretty hard. Sucks to be the world. (Also, James Marsters, yay!)

Charlotte revives and manages to find the tomb, but when she looks around, she finds the diamond - and Sutton - missing. She curses the count - her husband - and ruminates that he isn't the only one with big plans for world domination. (Presumably. I mean, why else would you go to such lengths?)

Only one member of the Last People On Earth was tried for the crimes of all, and he recently died in prison. Two others are the recent victims, and the final one, Autumn, is the head of a local environmental group. If things keep going the way they're going, she could be the next one on the hit list.

Forest Ranger Evan Smith - actually the brother of the LPE member who died in prison - has been using a lantern artifact to kill his targets. He gets the drop on Pete and Claudia, and manages to abduct Autumn and take her to a nearby logging site, owned by Mr. Lockheart, the man who was targeted by the LPE when they were active.

Just as Artie tells Myka and Pete that the artifact is probably Cupertino's medal, Abigail appears. Artie exploded at her when she, a former psychotherapist, suggested he talk about his grief. She's furious that he refuses to acknowledge the problem and insists that he wear Pancho Villa's boots in order to numb his pain and get on with his work. Artie's fury grows stronger, pushing Abigal to bring forth a painful memory of someone she tried to help, and couldn't. She has rage of her own, and it almost prompts her to quit on the spot.

Monty was absolutely crushed when he found out he didn't have real magic, but the agents figure they can take him on an exceptional tour of the warehouse. He promises to keep their secret, but he didn't promise he wouldn't steal Houdini's light bulb!

They discover that Rose is actually Monty's granddaughter and deduce that Rose must be controlling the artifact as a way to give her grandfather a "magnificent" end to his storied career.

Helena is trying to build a new life for herself with her boyfriend, Nate, and his young daughter, Adelaide, so she doesn't want to get involved in the investigation. When Myka pleads for her help, she obliges, and they find that it was the arresting detective who used the artifact that made the man turn Cro-Magnon

The detective, Briggs, knows something is up with Helena and visits her home to intimidate Nate. He uses the artifact, a hyena jawbone, to strike fear into Nate that's strong enough to transform him into a cave man. Myka and Helena arrive in time to bag the artifact and save him, but soon Briggs kidnaps Adelaide, and the stakes grow higher!
