Recently I ran across this image from the mini-series of Battlestar Galactica (from the scene in which Roslin is diagnosed with cancer):
My question is: Is this really supposed to be Serenity, the ship from Firefly? And, if so, how did this happen? (An out of universe explanation is welcome, since an in-universe explanation of Serenity doing a job on Caprica seems... far-fetched.)
