So who do we think the remaining staff are?

I saw a theory about Doey being Rich (shoutout to Tericho!) that I was really interested in, but now that's proven wrong I'm back to brainstorming over who Rich might be. He's definitely going to be key to the plot, I can't see them building up the suspense over this specific character just for him to be a minor background thing. Unless they're going to reveal at the end that Rich died somehow but idk, I feel like he'll be a toy

My current theory:

Elliott - prototype, I'm convinced now, will die on this hill

Rich - Player. Or someone equally important. He's been too consistently mentioned to be a side character.

Stella - Kissy??? I'm not sure about this one but Stella does feel like she'll be an ally to me

Leith - Huggy. I could also see Rich being Huggy but eh, the last tape made me suspect Leith a bit more. He was talking about security, after all

I'm definitely forgetting staff members, so let me know in the comments, which staff members do we still have to identify as toys? Who do you think they'll be? Tell me if you think I've got the lineup wrong, would love to hear your thoughts on this!
