im pretty sure that those grunts could/would kill people. That team has no morals at all. Titania is just frustrated that she lied to her best friend for all those years, then Amaria tries to kill herself, because like before, it was a lie and no one loved her (past trauma?). Then she gets kidnapped by the grunts. This just piled up for titania until it she couldn't control it. I'm not justifying her actions, she lied to amaria to prevent her from killing herself because no one loved her, like in the past. Now because of this trauma amaria's mind forced her to forget it, but we/she know that it will come back at some point.
