Jen and Lissa are back in their original world, and their "normal" appearance! Actually, did they even leave in the first place? It can be a bit hard to tell sometimes, what with the various illusory phenomena, transdimensional intersections, mischievous extraplanar entities, and any other manner of unusual effects they tend to encounter in their line of work as anomalous investigators. But sometimes that's just the way things go in the small yet surprisingly well-funded group of explorers of which they're members! Unlike that of the other organizations with which they sometimes must compete, the primary directive of Jen's and Lissa's group is to investigate strange occurrences in non-damaging ways, and occasionally to rescue and relocate non-hostile sapient anomalies: not all rival organizations share such sentiments, after all...

That aside, there's also the matter of how they became a doubletaur to begin with: I don't yet know all the details of how that went down, but I'm sure they'll tell that story in due time!
