I mostly think it's cute now. I don't want him with Buffy, really, but I think he and Dawn are good for each other.

Here's the thing: Dawn is the aggressor in the relationship so I think it's cool. And she's so clearly her own woman now that any age-factor squick doesn't bug me.

I think they're cute together. They're always being adorable in the background with one another. Like in Retreat when they were walking across a river and Xander tripped on stones and Dawn helped him. And then here where Dawn is freaking out and Xander's comforting her.

I can see how thinking about it is squicksome, but I find the reality cute and so ~not gross. Dawn is a grown woman and she wants Xander. She should have ~everything~ she wants.
