Indeed. Let's count it down.

So, Grimm are attracted to negative emotions, and dissipate into nothingness after a few hours. Seems [url=http://www.khwiki.com/Heartless]oddly familiar[/url] to me... Other than that, no big surprises beyond the expected possibility of new Grimm.

As for the most recent episode, Roman apparently has a grappling hook in his cane too, which is convenient. It's ironic that while he's the guy in charge, he goes down the easiest in the three fights we see. Also 1/6 roll for that Persuasion check. Try again next time.

Neo is awesome, Chainsaw Lieutenant isn't bad, that mysterious figure with the Grimm mask is certainly intriguing, since they apparently use blades made of pure Dust or something, and I bet it'll be suggested, but I don't actually think it's Summer Rose personally. Just a hunch, even if they did save Yang from being aggressively shanked before ripping a hole in reality to leave. 

Oobleck's coffee mug bat is also a flamethrower. Which is cool. And Zwei apparently has an aura of his own, since he gets hit with said bat, lit on fire, and smashed into a mech with nary a scorched hair on him. 

Now then...This plan doesn't seem very well thought out. Leading the Grimm to Vale I can understand, but after ramming through a wall, how were they expecting to unload all the stuff they had on that train before the Grimm caught up and started killing everything? Then again, I suppose the people inside the train weren't all knocked unconscious like Team RWBY was on the outside of the train.

Next week is gonna be a doozy.
