Warning: Spoiler Alert
Frank's explanation of what's been going on with him, the reason for the marks on his arm, and the reason why he was looking for the Hellfire stuffs ... I wish that I could trust that he was just trying to figure out some way to make sure that his family is taken care of with everything that is happening with Henry, but I don't. I'm highly suspicious of what is going on with him, and suspect that there is something on that flashdrive that shouldn't be out in the world. I have the feeling that Evil!Frank is very much in control and has learned how to make people think that he's just regular!Frank; if Evil!Frank is so much in control most of the time, I don't see how regular!Frank would be able to take enough control to realize that there was a way to keep the evilness away, look around for a way to make sure that he could stay in control for a while, and hatch a plan to make sure the wife and kid are taken care of. It seems like the evilness would realize there was something going on and would reassert its control ... but then, with his "rebirth," I'm not entirely convinced that there would be anything but the evilness in him anyway, what with his soul belonging to Henry.
I'm kind of glad that they were forced to blow up the Chamber of Secrets without having a chance to roam around and read everything that was in there. It would probably be helpful for them to have a better idea of what they need to do in the fight against evil, but I like the idea of the having to figure things out as they go long much more than having everything spelled out for them; besides which, having everything spelled out for them that way would mean that they were getting what Jefferson and Washington thought were important, and not necessarily what really was important (and their actions might have been colored negatively by that, making them possibly do something other than what their guts told them was the right thing to do). Even if there are times when they could really use some more information in a hurry about what they're dealing with, going with their guts when it comes to saving people (hunting things) has done them pretty well ... at least as far as when Katrina isn't involved.
And I'm not going to get into the fact that Jefferson was a hologram, Captain Skinnyjeans was able to run his hand through the hologram, and yet, the hologram was able to pick up things and carry them around (without giving us any kind of explanation about how that was possible; not even OMG!Magic!).
I'm so glad that it didn't turn out that the visit from Henry to Katrina didn't turn out to just be a dream, but I hate it when that sort of thing happens. It seems far too much like a giant FU to the audience (unless it's done very tongue-in-cheek like on "Newhart" or the last episode of "The Late, Late Show" that Craig Ferguson was on, where it's something self-aware ... where the writers and actors/performers are giving a giant wink to the people watching). And I'm also glad that it looks like Katrina is going to go all Dark Side, cuz it seems like it would be kind of awesome ... and maybe her character won't suck as much as it does right now.
