Uninvited Guest was an unnamed demon that tormented Candace, Jon, and Jacey St. Clair in the Season 9 Episode "Tunnel of Death ."
He/It resided in an old mining tunnel in Grundy, Virginia. In the spring of 2010, Candace and Jon St. Clair visited to do some ghost hunting. During the investigation, the demon sensed that Candace had a spiritual gift, and followed the couple back to the home they were moving in to.
"It was huge, I mean it had to be over 6 foot tall, and it had scales." - Candace St. Clair upon seeing it for the first time.
"When I looked up, it was like a gargoyle, but it had more leathery skin." - Candace St. Clair
"I'll never forget the face, because it seemed semi-human." - Candace St. Clair
"It looked like a person in the face, you know it just look distorted." - Jon St. Clair
UG was very violent and sadistic.
- Dream Manipulation - It can be implied that Jon's nightmare was caused by UG, since it seems coincidental that he'd have a nightmare about the same demon that Candace was seeing.
- Technology Manipulation
- Mind Control - Heavily implied to have used this on Jacey.
- Possession - It's never shown to do so, but it's reasonable to assume that as a demonic entity it can do this.
- Shapeshifting - Seen below, it morphed into Jacey.
- Supernatural Strength
- Teleportation/Supernatural Speed
- Since UG didn't follow Candace, it's possible that the demon just wanted the house and was being territorial.
- It was played by Tony Wade
