Where Aren't They Now: 7

It is difficult to discuss Anna without also mentioning Rebecca ("Becca"). Though the girls argued more often than they got along, they were rarely out of one another's presence through much of their adolescence. Theirs was a powerful bond that made many of their friends jealous; sometimes it felt as though they shared a single mind.

I should mention, of course, that the girls were not twins, or even sisters at all-- Anna and Becca were simply two girls that looked exceedingly similar. Blood tests have confirmed that there was no familial relation whatsoever.
