I just finished it and I loved it

I thought it was absolutely amazing, but I still have questions.

How are the Morleys connected to Elias?

Who thinks the loop actually stopped? In the end of the show you see that know you are loved pops up on the side of the building, so that gives the impression that the bomb is still about to go off. But how is she supposed to be paralysed?

Also, how is the future cop the one that was paralysed still there in 2023? Future Sahara actually disappeared, but for some reason the cop is still there driving the taxi.

anyone have theories or discussions?
