follow up question about the tracker! Ciri will end up digging it out of her arm, and in an effort to hide it, she'll try to hide it in Nero's tail (with Nero's permission) since its scaly and spiky. Even if his body tries to shove it out too, it'll be better hidden amongst the spikes than sticking out of her arm (or that's the idea, on their side).

Can it remain in his tail? Will they have to keep shoving it in there lol

Also will the signal keep working?

Thanks!
