I expected some bad blood to still remain between the girls and the Demon Queen after what went down during her Invasion, but it seems that I underestimated the girl's resolve quite a bit.
Elizabeth behaved politely, and while not at all meek, she stayed very quiet and showed a lot of modesty, only speaking when asked or when she felt necessary. It's very different from how she behaved when she first showed up, but it shows that she put in the effort to restrain her prideful nature and demonstrated her intent on fitting in and not causing trouble to anyone, which we all appreciated.
There were a few bumps in her way though... As was the case with the girls, this world was too different from what she was used to, which led to her being quite troubled by it. Still, I could tell that she was willing to try to follow and obey as she almost listened to Claire's unreasonable orders.
