— Frank to Dean Winchester
in Adventures In Babysitting
Frank Devereaux is/was a computer expert that Bobby Singer knew.
Frank is an expert in counterfeit documents and in avoiding government scrutiny. When he was 26, his wife and two children were killed. He knew Bobby Singer, who once saved his life in Port Huron. Frank lives in a run-down, electronics filled house on a little-traveled street.
In Slash Fiction, Bobby sends Sam and Dean Winchester to see Frank when two Leviathans are masquerading as the brothers. Sam and Dean enter Frank's house, and he is waiting in the dark with a shotgun. He is prepared to shoot them, but because he owes Bobby he agrees to help them. Frank believes that Leviathan Sam and Leviathan Dean are clones created by the government.
Frank advises that the boys go into hiding, maybe even move to Cuba, but Dean says they need to go "further off the grid, but keep us on the board" so they can hunt down the Leviathans. He tells them that they need to keep a lower profile, avoid security cameras, and to get rid of their rock star aliases, which are too easy to track. He smashes Sam's laptop, gives him a new one, and demands $5000 for it. He then takes their pictures for new IDs as Tom and John Smith and gives them a map of the towns their Leviathan doppelgangers have hit so far. Finally, Frank tells the brothers to leave the Impala behind, as they are driving one too.
In Adventures In Babysitting, Dean has given Frank the numbers 48495 which Bobby wrote on Sam's hand before he died and also asked him to research Dick Roman. Having not heard from him for a month, Dean returns to Frank's house to find it deserted. Frank confronts him, and they both have to shed some blood to prove to the other they are not a Leviathan.
Frank has moved all his equipment into an RV, feeling he was being watched after he started investigating Dick Roman. He tells Dean he has found nothing on Bobby's numbers, but then he tried combinations with adding a sixth number and realized they are coordinates to a field in Wisconsin, owned by Dick Roman.
Frank and Dean travel to the area and disguise themselves as phone company workers. They discover surveillance covering the area and retreat to Frank's RV to monitor it. They discover Amanda Willer, an employee of Dick Roman, surveying the site for construction. Frank challenges Dean about how he is running himself into the ground.
In Out With The Old, Frank talks with Dean by phone from his camper, updating Dean on Leviathan activity worldwide. He has no record of their activity in Portland, Oregon, where Sam and Dean are currently working, but Leviathans are there all the same. Frank discovers this when Dean asks him to investigates a company behind an odd realtor; the company links back to Dick Roman.
Sam and Dean set out to meet Frank at the end of the episode, but instead find his RV, filled with smashed electronics and blood.
In The Girl With The Dungeons and Dragons Tattoo, the Winchesters receive an email from Frank, which he prepared in the event of his death or worse, alerting them that someone is attempting to hack into his hard drive. The hard drive had been stolen by Dick Roman, and contained information about them, new aliases, hang outs, where the Impala is, etc. Charlie Bradbury, the IT employee assigned by Dick to crack the hard drive, eventually gets in and reads all of Frank's intel on the Leviathans.
Bobby describes Frank as a "jackass and a lunatic" but also as a surveillance expert. Frank describes himself as "bi-polar with delusional ideation".
- Season 7
- Though it seemed that Frank was killed by the Leviathans it is possible that he could still be alive, due to the nature of his paranoia he could have faked his death to avoid the Leviathans even if it meant not telling Sam and Dean. This is supported by the lack of a body and his email saying "If your reading this I'm dead, or worse" indicating he's not dead but believes he might as well be.
- Frank was possibly named after real-life Frank Devereaux, a man that was found dead in 1883 next to a body of a bear, with the ground around them trashed for 20 cubic feet. It is believed that the man and the animal brawled to death.
- Robbie Thompson wanted Frank to physically appear in The Girl With The Dungeons and Dragons Tattoo, but actor Kevin R. McNally was busy. This led to the creation of Charlie Bradbury.
