I never understood how Bart came to be
why didnt they just say that before Barry died, him and Iris did the dirty deed and then Bart was born instead of him being Barry and Iris's grandson from the future
But if Im correct it involves time traveling or something. Its just really weird to me
A comic twilight zone. Flash died in Crisis before his book canceled. So hi slast story 'took place in teh recent past'. It ended with Barry going to the Future with Iris. The Assumption then was that the two had several weeks or months with 30th century medicine solving any problems with producing heirs dealt with and Barry came back to the 20th Century to die before the twins were born.
Did they retcon that away????
