Marian hopes so. And she'll try very hard to help. 

At around ten pm Washington DC time, six pm in Alaska (time zones are a clever idea but a lot to get used to!) Leareth receives a message from one of the highway-watching teams. A known Yeerked human is headed back from some sort of day trip, along a remote road. They're driving alone. They'll reach the team in less than five minutes.

Is kidnapping them a go? Can they get the Andalite in Yeerk morph available right away to be Gated into their shielded camp so he can infest an animal (they've got a rabbit for that purpose and can try for a deer if needed?), acquire the human once they're Fetched and make a corpse? 

 Rilem-Elcar-Arreteth, who has a Yeerk morph, is available for this and has tested it so he knows it works.

He's not one of the Andalites with a Thoughtsensing amulet so everyone can read his thoughts, which are that he spends most of his time trying not to wish he'd never picked up a Yeerk morph. It is very valuable that he did. And soon everyone will have a Yeerk morph and it won't all fall on him.

Matirin communicates that kidnapping them is a go.

Leareth's mage, who was selected for this because he also has Farsight and Fetching, does a really fast Gate; his Farsight and the Healer's Thoughtsensing confirm that the car is still about four minutes away. They're behind shields, in a makeshift, not especially comfortable camp hidden by a tangle of blackberry bushes (strategically de-thorned in the bit they shove aside to get in and out.) 

They ready themselves. The mage uses Farsight to peek into the car, and readies his Fetching for a fast grab. 

When the car comes around the corner, the mage casts an illusion of a running deer, to get the car to swerve, and then adds a shove with magic, to make sure the car definitely going to lose control and roll over. They don't know if the Yeerks give their agents instantaneous modes of communication, but they don't intend to give them much of an opportunity. 

Osset 7780 brakes, swerves into the other lane, rolls, screams semi-voluntarily -

And then he is suddenly not in the car anymore - there's a brief but disorienting sense-of-falling before he thuds onto dead leaves, a force pinning him to the ground while someone else's hand reaches for his forehead. 

Rilem, inside a morph-capable rabbit, acquires the human and then focuses on morphing the rabbit into him - it's harder than morphing normally but not that much harder -

- and then he wiggles out of the human-shaped rabbit and demorphs as quickly as possible, shivering violently and trying to hide it. 

Dead leaves? That's not what would be expected if there were a discontinuity and then a hospital - was he thrown clear? can't move because the wind was knocked out of him - who is that - Dave is yelling at him for being a shitty driver, whose driving skills do you think these are, DAVE - oh he's drowsy now, maybe passing out -

And the Healer pushes with their Gift, and renders Osset 7780 unconscious. It takes about ten seconds. 

The rabbit-morphed human is killed with a blow to the head, and then Fetched into the car, now up against a tree and upside down. The car has not obligingly caught fire yet but that can be fixed with magic. As the party Gates out from under their shields - the shields themselves will persist for a few days but aren't detectable except to mage-sight, and they've packed up and left few other signs of their presence - the fuel tank can be heard exploding. 

Marian is waiting for them, Leareth at her side; she's been warned that the Yeerk-infested human being kidnapped may arrive with injuries, if they weren't Fetched from the car fast enough to avoid that. She tries to get a better look at them - are they bleeding? 

Bit his tongue a bit, that seems to be all.

Nayoki slips past Marian and, while the human is still being kept unconscious with Healing, gets to work. Set-command on the Yeerk to relinquish control of the human but stay put, and a block on the human, mostly to keep them from freaking out too much because that sounds exhausting right now, but she'll take it off after the Yeerk is removed. 

Aaaaaand let them wake up, while closely attending with Thoughtsensing to get both sets of thoughts. 

Leareth has quickly scanned the body for any technology that shows up to mage-sight, though if they have communications devices, the Yeerk shouldn't be capable of using them and the signal shouldn't be able to get out of their underground base. He mindreads as well. 

Dave does not expect to have control of his body when coming to so he doesn't do anything at first.

Osset assumes that they are finally in a hospital and Dave is on a LOT of drugs, like, SO many drugs, that are somehow interfering with his control? They must have gotten super fucked up in that crash. Osset considers for a while and decides against actually disabusing Dave of the notion that everything is normal.

Eventually Dave starts mentally yelling at Osset about swerving stupidly to avoid the deer. Dave is of the opinion that the car has crumple zones and could totally take a deer and then they wouldn't roll, they'd hit the airbag. Osset tells Dave that Dave would have done the same thing.

Donni arrives and casts a coercive Truth Spell. She's not actually sure if it'll hit the Yeerk or the human or both. 

:Do you have a communications device on you: a voice asks in Osset's head. 

...is that Visser Three thoughtspeaking him? Nobody else has ever Thoughtspoken anywhere Osset could hear so he's not sure if the voices differ much within or between people but this does sound different. They have Dave's phone but it probably broke in the crash. Maybe it didn't, they say Nokias are pretty tough.

This is an astonishingly unsuspicious Yeerk. Then again, most people aren't Leareth. 

Just in case, the phone is located and removed from Dave's pocket. 

:You are a prisoner: a different voice says in Dave-and-Osset's head. :You have been captured by an Andalite resistance force on Earth, your colleagues believe you to be dead, and you have no chance of escape: And to just the human, though the Yeerk will hear it as well: :Dave, we have the ability to force him to leave your head and will do so after preliminary questioning. In the meantime he does not have control of your body, though we may grant him back the ability to speak: 

Aw shit, thinks Osset. Should have hit the deer and killed the Andalite.

Dave adjusts his position a little, notices he isn't hurt. "...thanks?" he says, though he's abruptly unsure if he's going to ever see his family again or anything.

:Dave, I am giving your Yeerk the ability to speak through your mouth only, but if you wish to override him he will have to let you. It is important that we question him, though: And they aren't yet revealing that they can read thoughts, because both of their prisoners' thoughts might be more informative that way. She makes the modification to the set-command, now that she knows they work on Yeerks at all; it's a fiddly change that takes her a couple of minutes. 

"Osset," he's managed to snatch the Yeerk's name as well, finally, "give us an accounting of how you arrived on Earth and the circumstances under which Dave became your host." 

"I why are you answering him? shut up I don't tell me to shut up was born are these actually Andalites I thought they'd on the shut up pal that ship has sailed I'll get out of their way if they you idiot -" says Dave's mouth.

Wow that did not work as well as hoped at all! Can she untangle any of it from their respective thoughts? 

Dave does not appreciate Osset's existence at all but is pretty concerned that being captured by the opposite side means he gets memory-holed and leaves his kid without a dad and at least Osset has to hug the kids sometimes for cover. Osset is attempting to answer but doesn't know why he's doing that and doesn't exactly object to Dave interrupting and is not really trying to calm him down and get him out of the way; as anyone who has lived in Dave for this long would know, telling him to shut up doesn't work.

"Dave," Leareth says. "We are not going to hurt you. We will not be able to let you return home, at this time, but we will make sure your child is provided for, so that you can be reunited after the war, and if any opportunity is found to do so without suspicion, or if we decide to stop operating with secrecy, we will bring your family here as well." Pause. "- Do your family members also have Yeerks in their heads, and if not, are the Yeerks likely to do anything to them because of your supposed death?"
