Unlike most Ananasi, you appear completely human when in Homid. There are no telltale signs that a part of your genetic makeup involves members of the arachnid species. You still have pedipalps, but they can hide away completely, not even showing up on dental X-rays. Your blood, if examined, appears completely human, with no trace of foreign antigens in it. Any medical test, no matter how rigorous, would still prove you "human."
