The Disaster at Hexside

Chapter 12 - Ruby - a few days before

'Harmony Hope please come to the office now.' I hear over the screaming gremlin bell.
I smirk and raise my hand.
'Mr Mason, may I go check on her, since she's my sister?' I ask.
'Sure whatever I don't care....ZZZZZZZ' he replies. Mr Mason is a really chill teacher and doesn't really care what we do as long as we do our work. He also usually sleeps through all our lessons. I grab my bag and walk to the office. When I get there I hear the principal tell my parents that Harmony was skipping beastkeeping to go to bard classes. As my sister runs out of the office I smirk, knowing that this is one less thing to worry about, now I just have to focus on getting rid of the rest of the competition for the emperor's coven. I go back to class and wait for it to end, and then it's lunch. I rush around, scanning the tops of all the heads, looking for the pink of his hair. When I spot him, I grab his arm and drag him away. We go to the Beastkeeping classroom and close the door.
'What the Titan Ruby?!' Tristan exclaims. I ignore him.
'Harmony has definitely been expelled, so that's one less person to worry about. Now, I would like you to take out Avery and Lili. I don't care when, or how, just do it. Not tonight though. I know Harmony will be staying at your place for a bit, so don't do it there, as your brother could see.' I say. Tristan looks thoughtful.
'If we attack anyone else, the school will go on lockdown though.' He says. I raise an eyebrow.
'So?' I ask. He smiles.
'Lili will be in the Healing classroom, probably all day tomorrow, and she'll probably bring both Harmony and Avery. What if I get rid of all three of them?' He suggests. We both smirk. It sounds like Tristan wants to hurt them, I thought we said that he didn't want to. I don't know how to change it though... I wonder.
'Perfect.' I agree.
