Episode 20:

So Kumoko became Ariel's master in the future, eh?

I'm so looking forward to the "war" in the past. One blink and entire hundreds of soldiers will drop dead, lol.

That diplomat that Oht sent really cant be seen as anything but the desire to go to war. But I didn't quite get how Kumoko killed him. Thought it was poisoned wine at first.

My number 1 question as of this point is: WHY is Kumoko going to war with all of mankind in the present time?! If she wants to save earth, shouldn't she avoid an all-out extinction war? lol

But we can probably also rule out Kumoko having acquired human form - unless she chose that telecommunication spider on Ariel's shoulder for nostalgia's sake.
