Kaylee and Simon (the actors, anyway) are going to guest star on Tuesday's episode of Warehouse 13. SyFy Channel.
For those who haven't seen Warehouse 13, I would describe it as an over-the-top sci-fi show. Sort of a steampunk version of X-Files, except the adversarial elements come from the past and communicate to the present via ancient and not-so-ancient artifacts from the past. The heroes work out of a huge warehouse in South Dakota that greatly resembles the one seen at the end of Raiders of the Lost Ark.
