Okay, a somewhat slower episode but I really like the character development for Thomas Wayne and Marth Kane, as well as Thomas' sister, Patricia. Having never read a Batman comic, the only thing I really know about Bruce Wayne's parents is that they tend to die pretty early on. In the "Gotham" premiere, they're shot to death in the opening scene. This episode is some really nice layering of their characters. So, Thomas is pretty much a self-absorbed dick. Martha is a genuinely nice person and Patricia...is seriously fucked up.
As for Alistair Crowley, I think he's a very nice addition to an already fascinating rogues gallery of villains.
As for the ending, damn, I was just getting to like Mr. Pennyworth.
