Rescuing your best friend from the Phantom Zone be like…

Batman: Hrrn. 

Superman: … Or, should I say “Robot”?

Batman: Why? Because I’m not crying?

Superman: Bruce, maybe you don’t have enough RAM to understand this, but there is such thing as brotherly love.

A little nod to Clark calling Bruce his brother in canon recently. *winks*
