Oh boy. I'm late to the party, but I just have to post it - I couldn't help but think of Tomochin's recent CM throughout the whole episode...
I always told myself the world would be over the day we'd get Tomochin clones. I'm afraid the AKB0048 universe is done for.
With that said, they totally should have played Clone as an insert song. Okay, not possible due to different record companies.
