This episode pretty much consolidate the lore into one exposition dump. It explains the history of the plot device and the reason why the villains are obsessively hunting them down. I kind of like that they show the mental burden of taking in such knowledge, it's not like everyone can absorb it as it is. But that's the least of their problems, as the mastermind is making a move at the time they are most vulnerable. I have to say though, the series is showing noticeable upgrades these last few outings. I think heading into the final stretch, they have been putting more effort into production from now on. This just makes it more rewarding to stick around and see what they have in store next time.
