It's also worth noting that the standard of proof for granting an annulment due to the marriage never being consummated (in cases where no shared biological children of the couple exist) is that both parties sign an affidavit stating that the marriage was never consummated. That's it. As long as the parties are both willing to agree to a minor instance of perjury, there are no consummation police. So if the "annulment" is the only evidence the episode gave that the marriage was never consummated, it's not very good proof of anything other than Sam and Becky agreeing that if there was sex, it will never be spoken of again.
