You're so smart and you remember how your sister was split open in front of your eyes, how dad's head was blown off and you hear a phrase like "Wait for me and I'll explain everything." How can this all be explained? You're a maniacello who needs to be kept energized in an electric chair for at least half a year. And that's no consolation at all.
The girl has a good idea of friendship. You can't say anything.
Tears are just coming (a fragment when the Cat asked her to stop).
You watch this, you think, well, what the hell, when this series ends.
And the last episode remains - well, what is it, how quickly it all ended =)
