"If I have to." Mia frowned watching as Hermione began writing something.
"What're you doing?"
"I'm doing the Arithmancy equations. If you plan on changing the future, you
should be aware of what your success rate is, shouldn't you?" Her tone of self-righteousness
would have bristled Mia's fur if she was in her Animagus form. "Or have you already done
the equations?" Hermione frowned knowingly, her lips a tight line. "No? Oh, so you're just
jumping to conclusions, running head long into the fray, and going up against Death Eaters
to save your loved ones. Because that worked out so well for Harry. If I recall, it was an
action like that which caused Sirius's death."
"I brought him back."
"He wasn't the only one who died due to someone acting rashly without thinking
things through. You need to start thinking less like a Gryffindor right now and more like a
Ravenclaw."
"Actually, this time I was almost put in Slytherin," Mia pointed out.
"I'm ignoring that comment, thank you," Hermione replied haughtily. "Now, you'll
have to kill Bellatrix, Crouch Jr, and both Lestrange brothers. That's four rips in your soul.
Add that to Crabbe Sr, and that's five." She made a note on the parchment. "How many
Horcruxes would you be making for yourself then? Do we want to go with special items
like Voldemort? I always thought he was a bit obvious. Maybe use a seashell and throw it
in the ocean."
"Fine," Mia said with a growl, jumping to the point, "I don't have to kill them, but
I can stop them."
"How?" Hermione refused to make eye contact with Mia, continuing to write her
equations down. "Professor Dumbledore has prevented you from being able to tell anyone
anything about the future. And if you are able to get them put into Azkaban, they'll break
out. You know that. Crouch will escape as the Polyjuiced form of his mother, and Bellatrix
will escape with the Lestranges after Voldemort rises again."
"I don't know! I'll just... I'll get rid of them and then destroy the
Horcruxes before Voldemort can come back."
"With Bellatrix and the Lestranges captured, how do you expect to get into the vault
to get the cup?" Hermione asked. "Draco got it for you last time."
Shit. Mia had forgotten about access to the Lestrange vault.
