forgive me if this was mentioned ... thought of this last night as I was dozing off (yes a week later still thinking about this finale) 🙂

since we know scenes throughout the Return weren't linear in terms of time, it seems to me that the ending of 18 may not be the first time we saw that "time period" or "reality". Really any scene in the previous 17 eps could potentially be in the same "time period"/"reality" we see at the end of 18.  

Not sure which scenes that might be ... but just throwing that out there.
