Out of all the bad days Tatsuko has had in her life (of which there are many, as there are countless things that can get her in a Mood), this has got to be one of the worst. Sure, she may not like having been thrown in some weird prison or having people explore her brain, but she can live with it. Now, however, her crime has been deemed unforgivable, the restraints she was already not fond of have tightened, and she is being plagued by angry, admonishing voices. Not fun.
This had initially set her on a warpath, nearly tearing apart the prison in search of the wardens to give them a piece of her mind. However, no matter where or how hard she looked, she could find no trace of them. This did nothing to soothe Tatsuko's fury; on the contrary, it had incensed her even more, leading her to angrily stomp and mope around the prison until she reached the hall.
She flops facedown on one of the couches, taking up the entire seat, before groaning in frustration. This sucks.
