Rewind left a message for Chromedome.
"Your attention for a moment. This is Rewind, showing you edited footage from my database. I've probably got 0.8 seconds before game over, so hear me out. I've always been terrified that you'd die before I did, because you and me apart strikes me as intensely wrong. So promise me something. Be brave. And be strong. And keep going without me. And another thing: no more injecting. It will kill you. And remember: you deserve to be happy. The New Institute was the old you. You're a better person now—stubborn and frustrating, but wonderful. And to think, I will never see you again. One more thing—one last thing—because I don't say it enough: I love you."
