Just had a sudden thought…
In 223, Nea said he only needed Timcampy to help him – and then Link informed him that Tim had been destroyed by Apo.
In 222, we saw another Tim-like golem named Urcampy, residing with Lucia and Joe-sensei at the Campbell Mansion.
What if both Nea and Allen end up needing to go the Campbell mansion, Allen because he needs to speak with Katerina (and probably Bookman Sr.), and Nea because Ur is Tim’s backup?
That would resolve the issue of both of them trying to go different directions while they fight over control of Allen’s body.
Hm…just an idea.
