Thank you! I'm still a bit unsure about this one, but I have all these ideas about Willow and power that tend to come out in various ways...

time itself is only a matter of perception, and maybe she's always been there.

There's Jubal again - that tone he has when he says "Maybe I've always been here...?" as if he genuinely doesn't know itself, as if he just one day woke up in the villain role of a small chamber play in the middle of space. (Very Rosencrantz And Guildenstern Are Dead, that episode.)

but because once you realize you can kill a king, suddenly nothing in the world makes any sense.

Oh yes. It's very proto-Nietzsche (https://www.goodreads.com/quotes/22827-god-is-dead-god-remains-dead-and-we-have-killed). Macbeth does murder sleep.

be a River instead

Heh. My soundtrack for writing this was "Dragging Hooks" by the Cowboy Junkies.

Can't lose the taste of this river mud
Black water in my lungs
They say you can't step in the same river twice,
Well I been stepping in this one, seems like most of my life
So sharpen up those dragging hooks and pull that sheepshank tight
Cast into the water, boys, we're dragging for lost souls tonight...

Thanks again!
