Clark and Bruce are in an established relationship, after clearing the air and having to work really hard to trust each other. In an unexpected twist, Clark finds that he's pregnant with Bruce's baby. Cue the epic freak outs, with Alfred just happy Bruce will finally have a little one of his own.
Earlier, before the events of Batman v. Superman, Clark found another Kryptonian ship and secretly moved it to Antarctica, while also quietly collecting as much Kryptonian technology as he could to keep others from doing what Lex did.
When it comes close to Clark's due date, he and Bruce head up to the new Fortress of Solitude and eagerly await the arrival of their baby.
