Well, at the very least, we can say this episode really did manage to fit a lot of stuff into it all at once. New character, betrayal, and Genm shows off more of his arsenal.
Honestly, I didn't like the fact that Mr. Motorcycle betrayed Emu. I guess I should have seen it coming; the mysterious way he acts, his nickname 'coroner', and the events of the previous episode. Still, I was beginning to enjoy it. I was even beginning to look past how awkward it was that one Rider was driving another; I was kind of hoping the two of them would become very close partners. Looking more like a motorcycle than Accel did in Double really helps. But you know what? This show actually managed to make feel something when Emu was betrayed. I was shocked at the reveal, and I was probably suppose to feel that way, so well done show creators! Well done.
Also, I have to say, Genm wears those pink and green colors WAY better than Ex-Aid. And that bicycle looks way better as armor.
