Well seems like they made it clear enough to send a message to people. Yet vague enough that if they come back with a third season they can explain it away. Wasn't all that big in terms of how they decided to conclude it, but couldn't have expected much more than that.
Think Yuji and Shana should keep the silver acting like Konoe thing to themselves. Last thing Margery needs to know is that her arch nemesis acted like that at the end of the fight
. Really puts ones life into perspective.
Action wasn't bad though. But makes you worried with Shana and Carmel completely outclassed in this one. If it wasn't for some lucky breaks like being able to use the structure as a shield they would have been done for.
