Guys… After Keith learned about the Blade of Marmora and made the connection between his knife and the Galra, he started asking Coran questions about whether it was possible that the Galra had ever been on Earth. Coran replied that it would be obvious if the Galra were on Earth, but Keith makes a valid point.
“The Blue Lion was there. Did a Galra pilot the Blue Lion too?”
At that point, Lance steps out in all his beautifully pampered glory and changes the subject, and then Pidge calls everyone over to look at something she found.
Coran never answered Keith.
What if the pilot of the Blue Lion was Keith’s mom? What if that’s how it got to Earth, and how she met Keith’s dad?
