Intrestinger and intrestinger said Alice to the White Rabbit. Let us guess; Bitchlock chooses her three assistants, and Abby chooses Tirin and 7 of 9 as her assistants.

Never did agree with this whole 'prove ones innocence by trial of combat to the death'
If one was truly innocent, then how did they end up in that situation in the first place?
Plus, one may be innocent, butt a lousy fighter

Uh, oh ... both choose Tirin as her assistants. This will become the time paradoxon which melts down the spacetime universe, muah, muah, muah!

We, the readers, know that Abby is innocent: her only 'crime' was having a boyfriend that was 'distracting' her from her studies, so Bitchlock had the boyfriend killed and split Abby into two parts, banishing the 'rebellious' part and imprisoning the magical-protégé part
The same thing happened with Dabs: she was imprisoned fro impersonating the Queen, even though she was told to do it (because the Ambassador or foreign King wanted to fuck the queen), Dabs managed to trick the prick into either believing he had or 'convincing' him he didn't want to after all
