So, after seeing the latest 'Heroes' episode, and hearing about a slight tendency of actors on various shows to want to date co-workers, even if they're playing relatives, it just had to be time for this poll.
Most inappropriate TV family chemistry!
River and Simon Tam (Firefly)
Nathan and Peter Petrelli (Heroes)
Claire and Peter Petrelli (Heroes)
Maya and Alexandro (Heroes yet again)
Isabel and Max Evans (Roswell)
Marsha and Jan Brady (The Brady Bunch)
I did manage to resist adding Jason Priestley and Shannen Doherty somehow.
