Now I'm a little rusty in my understanding of the timeline of these people and when they died but I think there could be a chance of these people being more relevant in the story. I know that both Schuester and Dr Groph were there when Samantha ran into the MPD. So these character could have more relevance especially if origins Richtofen communicates with them to tell the changes they need to do at Griffin Station. Also about Peter McCain I'm not sure when he gets hanged or if Richtofen did it to him or he did it himself but I think it was after Richtofen teleports Samantha. So he could be invested in the new story as well. Maybe Origins Richtofen can use the fact Peter is undercover to his advantage. I mean this is speculation but I really feel that Schuester and Groph will be more involved as they are both at Griffin station (which I presume Origins Richtofen hasn't interfered with its creation) and both old Richtofen and Origins Richtofen have the same voice so he can change their orders. Also the Russian scientist (Yuri?) could be involved. I really hope they expand Der Riese so that we can uncover more secrets. Can anyone of you expand on this speculation (I not great at backing theories with evidence)?
