Ordered Timeline
a story beat for rees in season 1: under the order of warner the gatekeepers venture to the anyth to imprison a hacker who has been stealing millions of currency from a criminal net organisation in archeston, rees eventually tracks him down and imprisons him and goes on to have a difficult conversation with his wife who is disappointed in him saying she doesnt see much problem with what the hacker did, he stole the money from those who were already thieves and used the money to try and enjoy himself and make himself less lonely by giving it out to others and now all of that is taken away and rees is responsible for putting him in a cell with people who he probably stole from, is that really justice she pushes onto him which makes him think
“we seized all the criminal money, we can now put it to more proper use” rees
“what? to the oligarch? the heavens? and what will they do with it that they couldn’t already?” wife
after this she starts to look at him differently as if he is changed and slowly loses interest in the man he has become
by the end of season 1 rees becomes the standing keeper and is left in charge as warner disappears/dies and rogue is imprisoned
by season 2 we ofcourse find out that he stepped down at some point during the 10 year time jump and hence now why lace (maybe?) is in charge
