Lost:
Kate/Jack - They just had instant chemistry. I know, very unrealistic. But, eh!
Charlie/Claire - He's the only guy who seems to really talk to her. To everyone else, she's just the big pregnant lady.
Gilmore Girls:
Rory/Logan - I think this is going to be a very different relationship to Rory's past one. For one thing, Logan's not falling all over himself for her. This is the first guy I see having a lot in common with Rory. They can have real conversations because they both are fairly affluent in many topics.
Luke/Lorelai - This is the relationship I've been waiting to happen for the last 5 years.
Without A Trace:
Martin/Samantha - I just matched up the two because the hints of attraction were there and I didn't mind it.
Crossing Jordan:
Woody/Jordan - I just think they'd make a funny couple. His corny personality would contrast with Jordan's usual flat humour.
Alias:
Carrie/Marshall - Come on. Who doesn't love this couple?
Sark/Sydney - I'm not really expecting this to ever happen, but I want to see their competitve interaction return again.
