"I charted a Yeerk-removal spell but each spellbinder can only do it six times a day and it's a twelve minute charge."

"It would be really handy if there were Yeerks who weren't terrible who could help with planning but I suppose they probably don't write notes about it."

"Probably not. And if they can flawlessly impersonate their hosts I'm not sure even having a you chat with them is a good screening procedure for actual trustworthiness versus faking."

"Yeah, I don't think so."

<I can morph a creature with mind-reading abilities and do not strongly object to doing that to a Yeerk.>

"What about the host?"

<It would be preferable to get a Yeerk outside the host but, ah, compared to having a Yeerk...>

"I mean, yes, compared to that, but there's still an extent to which you can contain the damage, if your morph isn't selective."

<The morph is not selective and I agree it would be much preferable to force the Yeerk out first. This is academic without any way of identifying Yeerks who might be candidates ->

"Author is a conjurable parameter."

<...sorry, meaning...>

"If Yeerks can let their hosts write things I can likely tell the difference."

<Oooooh. That is much less invasive.>

"I mean, the Yeerk could still coerce the host into writing things, but it's a first pass. If it works. Merits testing."

<We can trivially acquire morphs using demon abilities.>

"Yep. Who wants to try this?"

Andalites shiver.

"This requires having someone morph a Yeerk and control someone else?"

<I cannot think of another way to do it.>

"Uh, I could like, maybe live with Bella doing it, but, uh, she can't turn into things and that's not super enthusiastic voluntarism."

<It is illegal but possible to share morph.>

"Lack of super enthusiastic voluntarism would still apply."

<I know.> Tail-swish. 

"Someone somewhere probably kinks on it. Unless Yeerks are reaaaaally gross. Are they."

"Slugs. Sort of an unpleasant color. Slimy."
