This is what Millie Bobby Brown was asked about by a reporter at the recent Q&A. It's from a gossip site, and I have no idea who wrote it. There are also mentions of this, by various users, in the comments to several relevant YouTube videos.

I do know, however, who wrote what you can find at the link below, because I did. It concerns a trip to the future, a friend from the past, a cyborg invasion, and a very young waitress on a space station.
