They're both in Miami, after all. I would LOVE to see them cross paths. They are both, in their own way, vigilantes.
And, in my sick little heart, I'm still hoping Dexter
will stumble across an incompetent CSI agent with red hair and sunglasses. OH, that would make me soooo happy.
Also, in the "NEVER IN A MILLION YEARS" category, I would love the Leverage
bunch to come across the now-retired A-Team.
A House/Lie to Me
crossover would be interesting, too. The male leads are basically the same character, so it would be interesting to see them go toe-to-toe.
