SomeKittens wishes they had copied down the phrase, but after Rey touches the Skywalker LIghtsaber, Maz ( really hope we get a book about her) mentions that those she is waiting for (her family) are in the past but there is one remaining for her in the future. The phrasing struck as Luke was the family member in her future for her.
If anyone sees TFA again, can you please get that line?
