Imagine your Harry Potter/Doctor Who/Sherlock/Anything OTP being canon. Even if they're already canon. It doesn't matter if one of them is dead, or if they hate each other, or if they have 16 children and have been married for years, OR IF ONE OF THEM MARRIED SOMEONE ELSE AND THE OTHER DECIDED TO SHAG THE OTHER COUPLES DAUGHTER *cough* .

Just imagine it.

Why?

Because it feels so damn amazing.
