((Tara, I know you are technically in control of which memories show and which ones don't, so let me know if you want me to change anything))
At first, Terenia does not react to Claxter's thought-speak. She is too immersed in her own memories to notice him. She is watching the scene of Efaen's infestation and the moments thereafter. She is listening to Efaen rage, then beg, then slowly become silent. Only Myitt can feel the emotions of this past version of herself, and Terenia is glad. She does not want Claxter or Ossanlin to feel the rush of excitement, the feeling of purpose that she gained from infesting Efaen, from stealing the limited shipboard Kandrona, from commandeering an Andalite fighter, from stealing away in the night.
Terenia realizes then that Claxter has made a request. Her memories flash forward, finally regaining focus a few weeks after Efaen's infestation.
The stolen Andalite fighter drifts through normal space, approaching what is unmistakably a Blade Ship. The communications device is activated and there is a hologram of a human being displayed. They are arguing. Abruptly the image shifts, and Visser Three's hologram can be seen.
<You wish to beg for mercy, Andalite?> he sneers, <I am afraid I cannot reward Andalites so foolhardy as to cross my path unprotected.>
<My presence here is no accident,> Terenia says with a scowl, <and I am no Andalite.>
Visser Three raises his brow, <are they accepting mentally deficient Andalites into the military now, as well as females? You are more foolish than most of your kind, but you are clearly an Andalite.>
<No,> Terenia insists, <I am Terenia Rerin, and I am here to claim my sister.>
For a moment the hologram flickers, as though the connection has been lost.
<Terenia?> Visser Three's voice is mocking now, <do you think me a fool? You are not Terenia.>
<I am,> Terenia says, <I can prove it. You made me kill my brother. You forced me to murder him. Then, you let me escape with Jennor.>
<Explain your current form,> Visser Three demands.
<I...> Terenia hesitates, then straightens, <that does not matter. Hand over my sister.>
<Or what? You'll shoot me? A single Andalite fighter against my entire Blade Ship? You will be obliterated.>
<I will stay,> Terenia says quickly, <I will help you. Just let her go.>
The Visser glares at her, calculating. Finally he snaps to someone unseen, <bring her in. Do a full memory dump and leave her in the holding cell.>
The scene flashes forward again. When everything clears Terenia is being unhooked from a machine very much like the one she is currently attached to. She has just completed a memory dump, and Visser Three's eyes are alight with malicious glee.
<You thought that to punish yourself, you would become a Yeerk?> Visser Three sneers. Terenia's eyes are downcast, <and then you ran away from the Andalites, even though they were the only ones protecting you?>
<They were making me infest people against their will,> Terenia says, <I couldn't...>
<Terenia, Terenia,> Visser Three shakes his head in mock sympathy, <you are more Yeerk than you realize. Is not the brain you are currently coiled around involuntary? Did she not beg for mercy, for freedom? Did you not dismiss her pleas as irrelevent?>
<I am not like you,> Terenia says, <give me my sister.>
<No, I don't think so,> Visser Three leans in close, <See, you need me. You need my Kandrona. No other Yeerk will take you in, and you have abandoned your Andalite allies. It would be cruel of me to send you out into the galaxy only to starve.>
<I want my sister!> Terenia cries, beginning to look panicked.
<Yes, yes, your dear sister,> Visser Three waves his hand dismissively, <go on, try to save her. Every time you fail, though, you will be punished for your misbehavior,> he sneers gleefully, <Oh yes, this is going to be quite fun. And, of course, my dear Yeerk friend, here is the best part. If you ever do succeed in saving your sister, I will kill you.>
