Before McGonagall can stop her Hermione looks in a mirror that shows what might have been but won't. She sees herself with small children and a loving older dark-haired man.

There would be dainty pink wand-patterned stockings, or boatlike men’s winter woolens: the socks of lovers uncourted, the socks of friends never made. Or dozens of baby booties to mock his empty mantelpiece, which overflowed with the photos of children and grandchildren never born.
