Geoff Johns started his career in Hollywood as Richard Donner's production assistant, which makes this collaboration an event on multiple levels. Admittedly, the plot isn't anything new: another Kryptonian appears and is taken away, Superman becomes fiercely defensive of said Kryptonian and adopts them as a family member. It happened with Supergirl, Power Girl, Supergirl II, and in a unique way, with the previous superboy, Connor Kent. This time, however, the adoption is literal-apparently Lois and Clark are going to be mom and dad.
