Well, francheeta, different eyes *do* see different things. I don't see any unusual chemistry in B&B, and I've seen nothing supporting a notion that they are "in love." I'd say they like one another, and care about one another's well-being, and working closely with someone typically engenders a kind of love. But all this is cut from a different emotive cloth than "falling in love."
And on a slightly different note, I don't know if it is possible to remove lust from "falling in love." To my mind, if a couple haven't fallen in lust, I'd have to doubt that they've fallen in love. But again, perhaps it's "different eyes...."
