Regarding the three-bears reaction to Willow - I personally fell between bears one and two. I think it needed one non-dialogue cue to make it sufficiently plain who 'Xander' really was, but thought maybe you'd rubbed it in too heavy. FWIW, anyway.

The part of this story that I read totally different to how it was intended was Tony and Jessica's meeting with Giles, and Xander's attitude to it. The way I interpreted it, Xander had gotten the DNA test results, discovered he wasn't a demon after all, and then basically washed his hands of the whole thing. It was Giles who felt a reluctant duty to let Xander's parents know (probably because he knew them least well of the Scoobs) and his excessive cold formality during their meeting was a very British sign of his distaste. Xander probably knew Giles was going, and had said something of the lines of 'yeah, whatever' when Giles broached the subject. And by the end of the meeting, Giles has basically abandoned his intended impartiality and is inwardly furious at the senior Harrises, but eventually recalls what Xander's told him about making a clean break and leaving the past in the past, and just gives up and leaves never to return...

Thanks for posting. It's always interesting to see how someone's thought processes work during the writing of something like this.
