Hi Morgana,
I almost missed the fact that you had commented. Sorry about that.
The spleen and left kidney. If they were regenerated as a result of his aura’s action on her body it is as yet undisclosed.
The spleen is an organ with limited functionality and an individual can exist with a single kidney so it really is unimportant if they regenerate or not.
Dr. M’benga knows her as Mrs. King. His documentation would simply have added to the mystery. No ointments, poultices or other materials were applied. The wounds simply disappeared.
RE: Clark of universe Alt1.
When the new universe was created it came into existence because Lois survived her injuries. The soul mate that she was ‘linked’ to was the 1997 Clark from Alt1. Because of that link he continued with her in the new universe -040 the new Alt, or perhaps Alt1Alt. Since he was the one to continue in Alt1Alt the original Alt1 Clark, the 1992 version, ceased to exist in Alt1Alt although he continued on in Alt1 to become the Alt1 Superman who was created by Lois Lane from Prime and outted by Tempus and subsequently went on the mission to save *his* Lois in 1992 and then continued on.
I don’t want to say anymore as it would be a spoiler.
