So my friend and I are members of both the Doctor Who and House fandoms, so when we were texting about our shows, a certain name came up which confused the entire conversation, then led to hilarity, crossover plotbunnies, and thoughts of "Why has no one done this???" on my part. I skipped back to 2007 and couldn't find it, so I assume it's new...
No spoilers, but putting it behind a cut in case it's large.
In case you don't watch House, the above is a doctor on the show known as "Thirteen," and for about a season her real name is a mystery. So my friend and I were like "lol what if Thirteen IS Thirteen, just to mess with people??" and "This means the Doctor's real name is Remy!" etc. It's a small thing, and I couldn't think of a very good joke for it, so if anyone else has a better suggestion, feel free. I just hope it brought some small laughs, if anything. :P
