She can't be fed magic if she's in hiding! Or kidnapped.

[it would serve her right to be kidnapped, actually]

...It's not the most charitable thought, but if the government has kidnapped her caravan I hope it makes her reflect upon her actions at least a little bit. So far she hasn't done much except inconvenience us and inconvenience the worlds that she throws us on. There's got to be a better way to get the magic that she's looking for.
