In what way, keeping in mind, if they are still alive, their story is not yet complete.

At the beginning of John 8 it says "many believed". By the end of John 8 these same "believers" were ready to stone our Lord Jesus. The simple change over them was Jesus stating who and what He was.

When our Lord Jesus asked Peter who He was there was no hesitation with Peter, "You are the Christ, the Son of the Living God". (Matt 16:16)

In John 8 you have those who wish to tag along until the message becomes difficult to hear much like the seed that gets thrown on the rocky soil. In Peter's case you have someone who doesn't need to be told what he already knows; he simply proclaims. Peter never "disbelieve". He was only unfaithful for the moment which our Lord Jesus predicted.

Did any of the first group become part of the second group? I don't know but I doubt it.
