Dad is your friendly neighbourhood dad.
Except also, he's not.

When the bombs fell, the world went to shit. The Fallout was intense, and people quickly took sides. In amongst the crowd were a couple from the suburbs: fresh, friendly, normal. They seemed the strangest choice to be chosen, but unusual times called for unusual measures...

And down the line, the two raised through the ranks:
Special Agent Dad, and Special Agent Mom.

Some say they were parents before they joined the Enclave, that it influenced their Codenames.
Some say they the Codenames came first, and the Wasteland got to their heads.
But you can count on one thing:
they're the nicest parents this side of what's left.~
