Oh, Draco... might as well give this rebellious business up for a bad job - if your mother thinks Weasley is a good match, you might as well go and buy yourself a wedding bouquet, going up against this woman is probably the worst idea you'll ever have - even the Dark Lord had learnt that lesson the hard way. :)
Heh, I love reading (and writing) Narcissa as a mother, there's not enough of her in the books. I think Tom Riddle didn't learn the right lesson that one time when he pissed off Lily Potter - how on earth did he think Narcissa would just stand there and watch her son fall to ruin is beyond me. :)
Momma knows best, Draco... Perhaps she figured out that male pregnancy thing and she wants some pure-blood babies... ;) I think Draco is up for quite a ride, poor oblivious blondie... :D
