Summerlilly agrees: What would you want to see?
I wouldn't really like to see it at all, I think. Sometimes the dead can be allowed to actually rest in peace.
Lets say Tara appears out of several reasons as a spirit while Kennedy and Willow are kissing each other. Then the three watch each other and say:
?(Well, what would who say?)
The thing is, I find myself fairly unable to think like a spirit, or imagine what a spirit thinks like. I think, though, that (within the premise of the show, not in the real world where I don't believe in spirits per se) by the time a person has gone from the physical world to the spirit world, the insecurities that come with being human will be gone. Thus, I think that there would be no stuttering on Tara's part. I think both Willow and Kennedy would be flustered.
If SpiritTara was in control of the appearance, I don't think she would appear while they were kissing at all. Why should she? What I
can see, is a spin on "The Killer in Me", where instead of Willow turning into Warren, Willow and Kennedy kissing made Tara's spirit appear.

The hex I cast lets the victim's subconscious pick the form of their punishment. It's always better than anything I can come up with. Elegant, you know?
That set-up, too, could have worked as a way to explore the guilt Willow feels over allowing Tara to slip from her mind for a moment. I think that guilt is very real to a lot of people who has experienced the death of a loved one. We come to a point where we realise that we are moving, even if it is slowly, towards a life where the wound after a loss is healing. It'll always leave a scar, the world will never be excactly the same as before, but we are going on, building a life where there is no longer an open space a perfect match for the person who died.
