Answer 1

All of the forces are the same as they are the manifestation of the same thing but under different symmetries, so yeah, that’s kinda of how they could be the same stuff.

>Did this single force then behave like all four at the same time?

You could say it only worked as Gravity and that the Weak force,Electromagnetism, the Strong nuclear force didn’t have their fields to work on.
