Muldoon's a former golden boy on the fast track at the Royal Dairy Bureau of Investigation who started seeing little green cheese whereever he looked. Now he's locked away in the basement investigating brie sightings and fending off dorky fans with no lives of their own.
Tully is a doctor originally assigned to Muldoon to help debunk his mysterious claims of the paranormal. But what she's witnessed over the years has challenged her beliefs in the infallibility of science and led her down a road of self discovery, forcing her to a painful personal revelation: "I could have been a radiologist and made five times this money!"
They make their first appearance in Episode 8, running into John, Monterey Jack and Scottish Mel while investigating yet another alien abduction claim.
