Now most of us know what and who Doctor Who is. A BBC show broadcasted for years in Britain and here the States. Throughout the years we've seen The Doctor regenerate and gain a two companion or two along the way. Come the start of the Tenth Doctor we a bit of an adventure. At one point we are introduced to Professor River Song (later Doctor Song.) which at this point when the Doctor meets her along with his then companion, Rose; that he has no idea who River is. Thus in my mind at least is the first nail in the proverbial coffin for our ever entertaining River.
Later on in the series, the Doctor as predicted regenerates into the Eleventh Doctor following River's death/self chosen and self imposed imprisonment in a virtual world. Of course we know that River's death isn't the last time the Doctor or us would see her. SHE'S PART TIME LORD!!!! Anyway I'll get back to that in a bit. The current Doctor, his new companion Amy and later on an additional companion Rory bump into River from time to time (or as the Doctor says whenever River calls him.) The Doctor reboots the universe with a second Big Bang. Followed by Amy and Rory's wedding, where the Doctor danced and bumps into his favorite bad girl.
After wedding and a trip to the Oval Office back during the start of the tumultous Nixon Administration (no judgment) with River diving off the 50th floor of the Empire State building in New York. So the second nail in the proverbial coffin, was just after the now famous River and Doctor kiss at her Stormcage cell. Clearly the Doctor didn't get the memo of simply just leaving it at he enjoyed the kissed, not showing any emotions and moved on instead of saying what he did. This way River wouldn't have had a sightly bruised ego. Hopefully that wasn't the last time for that like River made it seem after the Doctor flew away on the Tardis with her parents.
Oops, guess the cat is out of the bag now. As of June 11th (for the States at least) we now know that Dr. River Song is actually Melody Pond, thus adding three more things to her resume of being a Professor turned Doctor (despite what Churchill said in "The Pandorica Opens")/Murderer. River/Melody is the daughter of Amy Pond and Rory Williams. She's also as Vastra stated in "A Good Man Goes to War" that River/Melody is "human plus time lord". Thank you very much Amy and Rory for going all out on that wedding night of yours on the Tardis, now you're the proud parents of a half breed. What's makes this matter a bit more bizzarre is that River/Melody has a crush possibly an actual romantic relationship in the future with her mother's best friend/ imaginary friend who just so happens to be hundreds upon hundreds of years older than her. Guess the apple didn't fall far from the tree this time.
Well at least its safe to say that its never a dull moment on the Tardis when River drops in. Until late summer/early fall my fellow Doctor Who addicts. Until then "Spoilers".
