Altean Anastasia AU with Altean Lance and Plance.
Altea is destroyed but the Galra do not get to wipe out the entire race and conquer the universe. Zarkon is killed, though Haggar lives and plagues Alfors living family. Alfor and his wife are dead. But there are rumors that her younger brother, Lance, survived.
Pidge aided Lance in his and Allura’s escape but his pod was lost and crashed. He landed and was found by the Blade of Marmora with no memory of who he was before.
Years later, Pidge and Hunk hope to leave their current outpost with a candidate who can pass as the lost Prince Lance. Pidge and Hunk turn him into the perfect prince, although he seems to know things even they don’t know. Hunk is buttering up Allura’s cousin, Lotor, when Pidge realizes Lance is the real deal. And even more real are her feelings for him.
Allura is tired of being disappointed. Every time she thinks someone has found her darling baby brother, she’s disappointed. She refuses to entertain Pidge and Lance is hurt realizing Pidge had started all of this to get reward money from Allura.
Lance has it out with Haggar when Pidge comes to his rescue. They take Haggar on together but she’s too strong. Sensing their distress, Allura arrives and finishes the witch off for good so she can never hurt anyone ever again.
