But not always, Laura Vanderbilt plays both Earth-Smallville Kara and Indigo, I’d call that legacy casting, but Indigo is a completely different species from Earth-Smallville Kara so she isn’t really a doppleganger, not like Barry, Henry and Jay, where the reason they were born with different names is explained/implied (his mother’s maiden name and the fact sometimes people choose different names for their children).
