I was proposing that The Leah that was born with Luke in Ep 3 died. But they saved one of Padme’s eggs and some of darths sperm and had a tube baby 2 years later. And they named that kid Leah too. That will explain the 2 year difference between the twins. Also why those twins aren’t identical.
So…there were three eggs during the initial pregnancy?
Why so suprisded? She’s a alien after all.
