Seriously, so Elektra was a Skrull, and Luke and Jessica's baby looks like a Skrull, or at least is not completely human, who cares?

This isnt gonna affect too many people in the Marvel Universe. So theres a group of Skrulls on Earth impersonating people, it's been done before, remember Skrullverine? And you dont really think that the Initiative People wouldnt have been checking for possible shapeshifters in their group, especially after the trick Hulkling pulled in the Civil War? People were probably having blood tests while their powers were being checked out. Also, Skrulls have only had a limited success actually duplicating any actual powers, so the only people who are probably gonna be revealed as Skrulls now are the more physically powered people.

Only way this will change everything is if it's revealed that all the politicians who voted for the SHRA were actually Skrulls.
