Valentina was a few minutes into her fight and still testing the titan's abilities when she noticed that something was wrong. No one else seemed to notice or care, but with her enhanced senses the vampiress could feel it.
Faintly, she could sense her eardrums throb from slight pressure changes. Like a bass played loud and low from far away, a pulsing rhythm could be felt. It didn't leave her confused though, only concerned.
'Those pressure waves are almost certainly from Bessie's gravity. Shit, if she's fighting that means there's an issue in the castle.'
There was an irrational desire to rush back as soon as possible but she knew that it was a stupid idea. Leaving Lilli behind to deal with this monster would result in either mass destruction or a failure to stop it. Additionally, just letting it go was a foolish decision too. So the Archduchess settled for the next option.
