Once we get through two pages of Supergirl recapping her entire history and the reasons she can't reveal herself to the world, "Supergirl's Farewell to Earth!" offers one of the biggest pieces of Superdickery of the Silver Age, and poor Krypto gets roped into serving his wicked, conceited, insecure, jerk of a master to pull it off.
Consider: Supergirl is secretly saving kids in the woods when she's approached by Krypto, whom she's heard about but never met. Krypto takes to her and they have secret fun burrowing through mountains.
Don't worry, Krypto. We don't blame you for any of this.
