I'm afraid I don't know what part you mean there...regardless it's staying. As far as the ending, I can't see me rehashing the same distorted riff(s) another time around (especially without vocals). I've grown to love that outro more than the rest of the song now, and have just been looping it to listen to. I don't know why, but somber, sad, melancholy trippy music just gets to me the most.
