Whichever. I just suggested that as a possible title to give you an example.

The difference there is that the reason they weren't raised together was because of parental conflict. And once Meredith did know about Lexie (and got over the initial resentment), they got started on making those shared memories and then ended up having only a few years of them before Lexie died. But both Meredith and Lexie repeatedly referred to each other as their sister.
