"Pretty good. I've never heard that one before."
"I just made it up. You liked it? My favorites are the ones with the Heterodyne boys' dopey monsters—Punch and Judy."
Agatha and Theo [1]

Theopholous duMedd [pronounced doo-MEDD], or simply Theo, first appears in the story as Head Boy among the Castle Wulfenbach students. He is a known Spark. He is also well-liked, apparently for good reason, as he is a gifted storyteller and a genuinely nice guy. It eventually turns out that he is Agatha's cousin, as his mother was Serpentina Mongfish, Lucrezia's sister. He comments that until this fact is revealed, he like Agatha didn't have any living relatives of which he was aware. (It is mentioned in Agatha H. and the Airship City that duMedd Senior and Serpentina died twelve years previously while fighting air pirates.[2])

On Castle Wulfenbach Edit

When Agatha Clay is brought on board the airship winds up at the bottom of the social heap[3] in the castle's school, Theo takes her part, just as he had previously done with a social nobody named Gil.[4] Theo may have had a thing for Zulenna Luzhakna.[5] It is Theo who leads the student expedition into the Baron's labs to peek at the hive engine, after which he is assigned grease trap cleaning duty of indefinite duration. When he is caught using that time to build a machine to do it for him, an unwise Lackya brings him before the Baron—in a lab where the Baron is about to cut into Othar Tryggvassen's brain, an image duMedd does not appreciate.

After aiding in Agatha's escape, Theo himself escapes the airship, again encounters Othar and apparently lays another fine tale on him—one that features Agatha's family connection to the heroic Heterodyne Boys and what a big fan Theo is of Othar's exploits, but seems to overlook the fact that the Mongfish scion is a Spark himself .

In Mechanicsburg Edit


Theo in Mechanicsburg

A couple of months later, Theo resurfaces[6] in Mechanicsburg, arm in proverbial arm with Sleipnir O'Hara,[7] where they are collecting materials for a planned expedition to India to find his father's secret lab[8]. Their lingering distrust of Gil[9] is resolved after they overhear him declare his intentions to help Agatha.[10] Using the Heterodyne Device, Theo and Sleipnir rescue Gil from Captain Vole's attempt to nab him.[11]. With Zeetha, they accompany Gil into Castle Heterodyne and form part of his "pirate crew" for a short time,[12] but are soon wandering the castle on their own .

He assists in cleansing Agatha, Gil and Tarvek of their Hogfarb's Resplendent Immolation, and in process is briefly menaced by his aunt in Agatha's body, who announces that she was never very fond of her sister. Uh oh. Fortunately, Violetta is on hand to extract him from immediate danger.

He and Sleipnir then also help in transferring Von Pinm's mind into the body of an improved devil dog. The danger involved tests their relationship and demonstrates how deeply they care for each other.

After Theo is shot in the shoulder by Captain Vole, Gil takes him to recuperate at Mamma Gkika's. Sleipner of course comes along, and is rather peeved when she realizes that the establishment is not "just a beer house." Before things can progress any further, they are both knocked out by the ringing of the Doom Bell. They are presumably still in Mamma's when the Baron activates the Take-Five Bomb and time-freezes Mechanicsburg.

Outside world Edit

Professor Kaja Foglio has said that Theo's name was a joke based on his initial fate as a casualty during the exodus from Castle Wulfenbach[13], but that they grew so fond of him that his life was spared. Apparently some one is now watching out for him, or Othar might have shot the little Spark back in Volume 5 .
