Yes. Not a fan of the redemption arc idea for damien or Ryker
I suspect we might see Damien again after day 9, but somewhat subdued and regretful, and not for at least another week or two into the storyline, perhaps even a few months or a year. Redemption is unlikely, but due to MC's kind nature, I suspect MC might find a way to guide Damien to a better path somewhere down the road, but they will still not be friends or anywhere close.
Ryker's redemption is impossible, based on what's happened. We'll most likely see him again only through news coverage/footage, or at most, a
hospital or jail visit, just to understand what the hell is going on, and to find out who Ryker's boss is. That visit might be by MC himself, or by a friend/colleague of Rachael, Willabelle, or Valerie (these three are most likely candidates to push this part of the story forward). If MC makes the visit, we'll see it, otherwise, Ryker's revelations would be delivered by one of those who's closest to MC.
