Leareth runs exponents of two in his head for a while and...no he's too bleary to do this from scratch and doesn't have it memorized that high, but - that's not even in the millions, it's in the billions... 

:I can get you...three doublings. For now. And you - need to go slowly. Carefully. Minimal damage: 

:Do you understand that: 

   ?

Leareth can't tell if that's meant to be a cryptic answer to his question, or if it really is a complete non-sequitur. He's also very sleepy again and his head hurts. 

He can think some prime numbers back. It's not as shiny but maybe it'll keep the alien happy for a while. 

(After a couple of minutes of this he falls asleep.) 

The protomolecule keeps growing.

Shavri snatches naps, and feeds it more rabbits until all of the rabbits are infected, and figures out that Nayoki is somewhere on the surface and within her Mindspeech range so she can ask after Jisa.

She and the Healers regularly check each other and all the non-patient-occupied room surfaces for any sign of Proto. 

It doesn't seem to be airborne yet - it only makes it onto surfaces when someone vomits, or pees, or bleeds, though the rabbits do all of these things as they get more infected.

Shavri is inclined to let the Proto do what it wants to rabbits as long as it's not killing her human patients. She suggests they turn one of the stone side rooms into a rabbit-quarantine-zone so they don't need to worry about every single surface in the room ending up contaminated. 

She swaps her attention between the two human patients as they sleep, feeding them Healing-energy, checking them over for any new Proto damage, fixing what she can or pointing it out to the other Healers. She seems a lot better at using her Sight on the Proto, maybe just from her additional two days' of practice. 

Leareth sleeps uneasily, half-woken every once in a while when he starts coughing or some new body part is hurting. At one point he manages to vomit in his bed again, too half-asleep to take any actions to avoid this.

He feels more and more...not just tired, but fuzzy-headed, and oddly weak and heavy, as though his limbs are turning to waterlogged driftwood. It's harder to remember where he is, or what he's doing here. 

There's a lot of protomolecule in him. It's growing a lot faster than in Julie, maybe because it keeps eating his reserves.

It's not trying to hurt him but it doesn't, actually, know much about how humans work, and he's made of all these yummy stable replicators, and it is recruiting a lot of them.

Shavri is definitely worried! When she notices specific damage it's doing, she tries to tell the Proto what not to do, but she has a feeling a lot of the mess is happening at a scale that's smaller than even her Sight can reach. 

...also they have a growing problem with the part where they squashed his immune system to stop it from attacking the Proto, which is that now half a dozen garden-variety opportunistic infections are trying to sneak in through the gaps, and killing them is doable but it's hard for even all of the Healers together to keep up. 

She helps them try to wake him and get some sugary water into him. 

Leareth is so unhappy to be woken, and it turns out that he cannot, actually, keep down any fluids. 

He's just barely lucid enough to think the beginning of the Fibonacci sequence at the Proto, and not quite enough to form words to communicate with the humans in the room. He meant to tell them to feed the Proto more cows. Cows and Gate-energy. It's important. He can't remember why. 

He drifts away into fog as soon as people stop talking at him. 

They try to wake him again in a candlemark. He's unresponsive. 

Shavri is quickly headed from frustrated to FURIOUS. 

:You're hurting him: she tells the Proto, angrily. :You have to stop it:

:You like talking about math, right? You can't do that if he dies!: 

She's trying to figure out what's even there to fix, here. 

There's definitely something pervasively wrong, in his body, but it's still too diffuse for her Sight to narrow in on. His pulse is weak and irregular, but she can't figure out why, there doesn't seem to be anything structurally wrong with his heart... 

While she's deep in trance, Looking, he stops breathing. 

:Damn it!: 

She grabs a hopefully-non-Proto'd part of his arm and shakes him, pinches him hard, taps at his mind hard with Mindspeech. 

He twitches and takes a breath, but he's still not waking up at all. 

:Stop it!: she shouts at the Proto. :Just stop. Stop doing any things -: 

It does that! All of it, not just the bits in Leareth.

:Thank you: 

And she focuses on pouring Healing-energy into Leareth, trying to stabilize his faltering heartbeat, steady his breathing - 

It's almost enough. 

Almost, but not quite.
