I'm currently obsessed with Buffy the Vampire Slayer, so I'd have to say:
Buffy & Angel
But Honorable Mentions go to:
Sherlock & Watson (from BBC's Sherlock)
Shawn & Gus (from USA's Psych)
Patrick Jane and Teresa Lisbon from The Mentalist.
Sam and Dean - brothers in Supernatural.
All the clones in Orphan Black and Felix.
Peggy & Don in Mad Men
Arya and The Hound in Game of Thrones
and what show is it from?
