we love Tara
I can't see Willow and Kennedy being together for long. With Tara and Willow there was a much deeper and spiritual contection they shared, and with Kennedy it seems much more physical. Kennedy seems to be the rebound girl, helping Willow cope and get over the loss of Tara, to help her understand that she can move on and it's alright. However, who knows, we did get to see Willow and Tara's relationship grow over a couple of seasons, as opposed to a few episodes with Kennedy. Maybe with more time is will seem more stable.
