Auxiliary Kaja avatarEdit

In terms of ethnic extraction, Sleipnir's first name is Norse and her last name is Irish. The same was true of Professora Foglio (her maiden name being Murphy). This suggests that Sleipnir, who is involved with the plot — where the actual "Prof. Kaja Foglio" so far is not — may function as an avatar of Kaja Foglio as well.

Sleipnir is not a spark but a mechanic who likes to hang around sparks; Kaja has expressed[citation needed] the feeling that she is not a scientist but a fan of science.

Relationship to Theopholous DuMeddEdit

Although when we first see Sleipnir, she says that she is looking forward to her marriage to a minor spark as arranged by the Baron, since then dramatic events which she witnessed are likely to have affected her relationship to the Baron adversely. The apparent death of Punch and Judy at the hands of von Pinn, and Klaus' continued pursuit of Agatha in spite of her remonstrances, chief among them.

Thus, it is not at all impossible that she has abandoned her engagement to someone she may well have never met for an involvement with someone with whom she has apparently shared a long and dangerous journey. It is, however, equally possible that they are only posing as a married couple to save money on hotel accomodations (or as a couple; this is Europe, and so the Smith Act does not apply). Either case would be consistent with the fact that she has removed her braids, which, in a number of cultures serve as an indication that a woman is younger than the age of marriage.

More telling is she is very concerned with whose goose bumps Theo is looking at.

Midnightchemist's entry states that the Foglios have answered the question: Sleipnir and Theo eloped. Whether or not they actually got married or just ran off together is still to be seen, but it appears that her previously arranged marriage is off the table (and the Foglios said they didn't consider it a major plot point anyway).

Their relationship is expanded in Agatha H and the Airship City with Slephir making a comment of looking for her shows under Theo's bed.--FossilLord 17:13, May 11, 2014 (UTC)

O-ta-ku connectionEdit

The manga Oh My Goddess!, which began serialization in 1988, is loosely based on Norse mythology and includes periodic cameos by (the equine) Sleipnir.

Outside information the possible relevance of which is even more remoteEdit

In the myth relating the procreation of Odin's octopodal horse, Sleipnir, the horse's sire is Svaðilfari, a stallion belonging to an unnamed rime (frost) giant, but his dam is the god Loki (who had taken the form of a mare, obviously in estrus, in order to hinder the giant).
