Yukarin... yea. It just makes Suzuha melts me, with her different range and tone of voices.
I also laughed at Okabe for his failed racism, serves him right to sterotype. It was a nice breather episode, there's been too much of Mayuri dying, so they need a break to group up and think of something. But those guys aren't making it easy.
And the future... crappy future indeed. Does one of the timelines lead to terminator?
