Whooee! I wasn't the one that started the rumour and I thought it was unlikely that Susan would bleach her hair - that silvery blonde didn't come out of a bottle (unless DiTo can tell us different). Don't they look great together though?
I know it might still be early days in Susan's timeline, but I still see no 'bump' showing - is Milly's minx of a sister into fibbing and interfering with Milly's romantic fancies? Alternatively, if she's definitely preggers but not far enough along to show, maybe she forgot what happened on her trip when the Federal Air Marshal plied her with champagne and initiated her into the 'Mile High Club'
