I am relatively new to the current supergirl saga. That said, I do have a question that I hope can be answered through comic book physics.
In the final issue, 80, Linda Danvers has been living a number of years in the other universe and started a family. She has a daughter that appears to be atleast four to six years old. Wouldn't her older age immediately be apparent to her mother when she comes and visits her new baby brother, Wally, upon her return?
No.
How old was "linda?"
I know that most folk look the same for about 15 years after they mature barring accident sickness or injury.
Linda was grown.
