The twins try to behave normally with their father or his pod person, whichever the person who calls them is, for a value of "normally" that involves adamantly continuing to want nothing to do with the Sharing.
And sometimes crying and refusing to tell Renée what's wrong.
School proceeds. No one's grades see more than a minor downturn as a result of all the alien business.
Andi and Robin play music. Andi's getting pretty good on the drums, although her teacher moves away and she has to hunt up another one, who she sticks with for four lessons before deciding to go self-taught.
Bella tightens up her cipher. It began as a letter substitution and since then has evolved to include plenty of personal shorthand - she turns the ratio of shorthand to straightforward letters up as far as she can and still read the thing herself. She abbreviates, she leaves out spaces, she names things in roundabout ways, she refers to things many notebooks ago that she can find easily that anyone else could spend hours hunting for, if she has to record names she finds ways to describe the spelling without ever placing all of the characters in sequence. Maybe the aliens have super-cryptanalysis and super-OCR and can eat her notebooks in one bite and know everything they know; but maybe not, and maybe if she's careful enough she'll look like she's writing her paranoid diary and not like she's taking notes on the quiet invasion.
Trouble comes over a lot. He stays over a lot. Renée has a quiet conversation about him with Bella, in which Bella is vague, pretends ignorance, suggests that maybe he just likes it here, maybe his folks are allergic to gluten and won't eat his baked goods? Renée leaves it alone.
May begins.
<Run. They mustn't catch you.>
Impulsively, he kisses the palm of the alien's hand.
Then he runs.
The third ship is darker still.
It descends slowly, directly over the stack of concrete pipe sections where Trouble tried to take cover earlier. Just when it looks like it's about to hit the topmost pipe in the stack, there is a flash and a kind of screamy whoosh—TSEEEWWW—and the whole stack vaporizes. As it settles to the ground, its shape is finally visible, silhouetted against the pale gravel: a main shaft like an axe handle and two sweeping fixed wings like blades. Near the forward end, where the handle bulges into a triangular spearpoint, a door opens.
<If you are still in range of my voice,> he tells the three remaining teenagers - Robin and Ethan are long gone - <be silent. Hork-Bajir have bad night vision but excellent hearing.>
Next, a pair of huge wormy creatures, twelve-foot-long pale grubs with dozens of short spiky legs set in a row along each side. The forward third of each tubelike body arches off the ground, bringing to bear two rows of smaller limbs tipped with more manipulatory claws, and terminates in a huge round mouth with four blobby red eyes set around the outside and hundreds of sharp little teeth ringing the interior.
The Hork-Bajir spread out, taking up guard positions around the empty area. But none of them seems able to see anything outside the circle of illumination provided by those blood-red spotlights.
<You have seen the Hork-Bajir. They are the Yeerks' shock troops. The Taxxons are the long creatures with the numerous legs; they are almost exclusively voluntary Controllers, motivated by promises of food. Always hungry, often cannibals. Excellent reflexes.>
<That is the only Andalite who has ever been taken alive by the Yeerks. The only Andalite-Controller. Visser Three.>
<Prince Elfangor-Sirinial-Shamtul, if I am not mistaken. An honour to meet you,> he says mockingly. His silent voice is very distinct from the Andalite's. There is no doubt as to who is speaking.
He doesn't answer Visser Three.
The question doesn't sound so much like he's curious as that he has chosen a question-shaped way to voice sorrow.
<Humans are many,> says Visser Three, stalking closer to Elfangor. <Many and weak. Billions of bodies, waiting in helpless ignorance for the Yeerks who will control them. We'll have to build a thousand new Yeerk pools just to infest them all. With this many hosts, we can spread throughout the universe. Unstoppable! Glorious!>
<I promise you this, Elfangor,> the Visser continues silkily. <When we have this planet, when we move against your homeworld with our fresh army of human-Controllers, I will personally hunt down your family. I will personally oversee the placement of my most faithful lieutenants in their heads. And I will require detailed reports on how their minds scream when they try and fail to resist.>
Elfangor's tail flashes forward. The motion is almost too swift to see, but it's illuminated with a sudden light-flash from the tail of his ship, which fires at one of the small Yeerk fighters and obliterates it.
<Fire!> he screams, presumably to his subordinates. <Burn his ship!>
Tight red beams from the big ship and the remaining fighter spear the Andalite's damaged craft, with that same familiar TSEEEWWWWW. It glows, then disintegrates slowly, leaving behind a yellow-white ghost for a few seconds. A wave of heat rolls over the surrounding area, not quite blistering by the time it reaches the hidden observers.
<Hold him for me,> Visser Three orders. Three of the Hork-Bajir scramble to obey, grabbing Elfangor's arms and tail and forcing him to the ground, one holding a wrist blade to his throat.
<You must not interfere. He must not see you,> he tells the kids.
His head grows larger. His legs slide toward each other along his body, meet, and merge into two thick trunks. His delicate arms sprout into vast curling tentacles. His mouthless face splits into a huge fanged grin. He grows taller and taller, twelve feet, then twenty.
He emits a roar that shakes the ground and rattles the skeletal buildings around them.
One of his long thick tentacles wraps around Elfangor's neck and hoists him casually out of the grip of the three Hork-Bajir.
Elfangor cannot restrain a generally-broadcast cry of pain, or fear, or despair - but his tail never stills once it's freed; he slashes at the monster that Visser Three has turned into.
