When am I likely to see WBW used?
You're most likely to see WBW used in discussions of how (and big spoiler alert here) the character Ben Solo (aka Kylo Ren) can return from his death in Star Wars: The Rise of Skywalker. Many fans believe Ben and Rey's connection is facilitated by the WBW, and that Rey could use the WBW to somehow resurrect or retrieve Ben from a point in the past.

How is WBW different than TBT?
As you may already know, social media users also post pictures and anecdotes from the past on Throwback Thursday (TBT).

However, WBW posts tend to focus on items from further back in the past than TBT posts.
