The answer to both of your questions is Saturday. I suppose this is as good a time as any to show that the chapters follow a pattern. Two Silas chapters and one Brady chapter. If you're looking for the band to come back just look to every third chapter.
As for Adelaide . . . I've mentioned elsewhere that I know nothing about dogs, at all. But this story wouldn't have worked out without her, and so I had to write a dog. I don't know how well I did, but it seems that for the most part no one is complaining.
And when it comes to being bisexual . . . I used to identify as bisexual before I learned that pansexuality was a thing, and I received that kind of abuse from people often. There are several other stories I've written that follow bisexual teens, and that's part of the reason why I wrote them. We're all normal, we're all here, and we shouldn't let anyone try and take that from us.
