Johnny-boy has once again seen Dracula being Weird(TM) and at this point, I'm sure he's doing it to brag, namely going out "in his lizard fashion". Which sounds like Dracula is wearing a suit covered in shimmering scales, which sounds fancy as all fuck and totally like something he should wear to ESC.
With his newfound situational savvy, Jonathan uses Dracula's absence to try and break out. However, he only succeeds in entering a so-far unknown wing of the castle which he thinks was "occupied by the ladies in bygone days" ...yeah, right. We get a neat description of how the stronghold is doing a good job of holding strong, and then our Victorian himbo is waxing poetic about moonlight for a bit (that's what a vampire's company will do to you, wake up your inner Novalis) and then presumably falls asleep because we break off pretty much in the middle of his musings on past and loneliness.
*pulls a moth-eaten blanket over Jonathan's shoulders* Queer dreams, sweetheart. As far as I'm informed, you're gonna need them. Because the shit is about to hit the fan.
