Those two Abyssals over there are at each other throat because of the grudge from the old times, they don't have any reason to fight Hysteria even if Miria do manage to drag her towards them. It's like the repetition of how Deneve and Helen were trying to loose Priscilla by drawing her towards the Destroyer only this time there isn't even any reason for it to work.
I want this fight to end already, the previous battles around the Destroyer were epic but this one just feels boring because I don't feel anything about those 3 newcomers to the series and I have a feeling that it will all end with some kind of Deus Ex Machina when either Priscilla or Clare drop by to break the party and everything that Miria and her team are doing now is just a pointless filler.
