Ut Malum Pluvia

See, we all ended up feeling the same way. That's why I found out, eventually, that we all left. My sister Vanya wrote a tell-all book about it - I read it in the library ruins while I was stuck in the apocalypse. Diego left, first to join the police, then he went vigilante. Allison became a movie star. Klaus just ... drifted in and out of rehab because drugs were the only way he could avoid his power, poor idiot. And you already know about Luther and the moon. We were all kinda scattered to the winds, living our lives ... until we found out he died. The day I came back from the Commission was the day of his funeral. Luther and Diego got in a fight over whether or not Dad had been murdered. Luther was convinced he had been. Diego wasn't. But I was too determined to stop the apocalypse to care either way.

[he sips at his drink, taking a slow breath once he's swallowed. he's had so much time to think about this, and it still absolutely stymies him]

Turns out they were both wrong. Klaus got a chance to talk to Dad's spirit, right before everything started going haywire. He fucking killed himself, because he knew it was the only way to get us all back together again so that we could save the world. You want to talk about control - [he snorts, flailing a hand in the air] - well.

Reginald Hargreeves could probably be your posthumous poster child.
