I was about to replay that part, just finished replaying ep9. Now I'm sure it not just random name. At first I thought that Stephen rejected Maya application even though he said to Sage that would consider it because Maya joined the HOTs, and we even discussed that maybe was something to do with Quinn, but now it makes me wonder if it wasn't because he saw where the money is coming from.
EDIT: Ok so I was rewatching that flash back and Stephen says to his psychiatrist that "started 8 years ago" by the same time Jade started her PhD and from what I understood they've adopted when she was halfway through, which should be 1-2 years after, so 6 years before the flashback. Sage should be around 22-23 during the events of the game, she kept her name Morgan so she were self conscious when she was adopted, anyone have any idea what age that would be? I'm guessing around 6 (?) supposing that somehow that's right, during the flashback Sage would be ~12yo (or adoption age + 6), which means that the flashback was happening 10 years ago (not from now, probably from 2018-19, the game release, because Stephen was using one of those phones that slided for keyboard, kind of a BlackBerry) which also matches subprime crisis.
His boss back then should be around his late 40s or early 50s, let's say 50. MC was 9, 9 years before he would have been 41 and Lynette should be around 20 when she had MC, so he would have been father at 21, is not that far off.
