Wow, some folks need to chill!
I've always thought that SnL are a fascinating couple and I think they do have a great "tragic romance" trajectory, especially Stevie since as far as we know she is alone and can't have Lindsey anymore except as a friend. Speculating about their feelings for each other is fun and I've certainly indulged myself on that end, eh? Heaven knows I have been given a hard time about it in the days of yore, which some of you may recall.
The thing is, we can't know. We know what they say, but even that can be ambiguous or even contradictory. When something can't be proven, there will be varying opinions on it. As long as no one's a jerk about it, I don't see a problem.
