All of her sequences are new. So -
2, 4, 6: NO.
Incredible.
She would have gotten this faster if she hadn’t been thinking about it as a kind of fucking math. Or if she had been a five-year-old. Or if she had been dumber.
Well, she can probably learn to be dumb sometimes, if that’s what it takes.
3, 5, 7. Guess: Outputs "YES" when given a new sequence; outputs "NO" when given a sequence already used.
NO. CORRECT.
She doesn’t collapse in panicked relief on her desk, because she’s not actually five and also that would be disobeying instructions about leaking information. She stares ahead, outwardly calm - which is probably in itself leaking information, because she probably unintentionally leaked a bunch of distress everywhere right around 1, 2, 3, 4. In any case, her soul is crying out in relief, and she gets a sympathetic mental pat from Pretender about it.
Only then does she look around, and see that all of the other new students are still writing. Some of the old researchers - including, of course, the Chosen - have stopped writing, but not all of them.
She really doesn’t know how to feel about this.
