I am confusion (c)

What happened exactly?

I've been onboard all the way up until this episode, it got a little too tangled for me tbh. Kevin agreed to drown so he could find the lady's kids, Evie + get the song for his dad so his dad could stop the rain.

And he entered this realm where he's an assassin and has an identical twin who's the president of the USA, and he switches between their bodies by staring into blank surfaces?

#ok

And Patti?

And after he killed himself he came back to our world, where doomsday now has passed - and everybody's feeling LOST? hehe

I dunno, dug the ep but I don't think I fully got what went down
