There’s a longstanding tradition of secrecy associated with the Star Wars saga.
From the (SPOILER ALERT) reveal of Darth Vader as Luke Skywalker’s father during the events of Empire Strikes Back, to the death of Han Solo at the hands of Kylo Ren in The Force Awakens, Star Wars has become one of the most consistently secretive franchises in the history of the modern blockbuster.
It’s not remotely surprising that Daisy Ridley isn’t giving us much information.
If that tradition holds firm for the next year, then we likely won’t learn exactly who left Rey on Jakku until we’re actually sitting in theaters watching Episode VIII.
