I noticed that it was a shorter episode too
I was thinking the same and maybe it was even edited different, like the scene with Tommy happening before the scene with Flynn and Warren to show a happy ending then a flashforward that was taken out
And we don’t know when they were greenlit for season 2, so maybe they had time to do that.... Or maybe that’s the ending we’d have got regardless of whether there was a season two, a dramatic twist at the end. Who knows?! (We probably never will to be honest
)
