"My baby's a girl"
Now that I did not see coming. Like most people, I assume Ao's older sister is Elena. Speaking of Elena, I laughed so hard when she hit Truth instead of Eureka. Ao thanking her for it was the icing on the cake
Naru's development is interesting. I remember somebody had speculated that she would end up piloting the TypeTheEND, he was pretty close. I'm looking forward to what she will do in future episodes.
