Oof, I mean, CGI can go a long way, but still... some actors stay young-looking (Johnny Depp did, for a long time), but it's a large cast and not all of them will. And they have to do it for an entire season, which gets expensive.

But, we'll see. My money's on a fast-forward into the 90's, like someone else suggested.

Honestly it’s not that hard, they just use clothing and makeup to disguise their height and age. Works really well for the most part.

How so? Like the ones they've done before? The season jumps ahead a few years? That's what I'm expecting; I guess I'm saying it's not quite right still calling them "kids."

They could do something like X-Men: Days of Future Past, where the Earth has become a sort out Vecna hellish nightmare and they go back in time to fix it, maybe run into their younger selves, or around themselves, like the DS-9 episode Trials and Tribble-ations. It'd be a pretty sad knock-off plot device, and it'd be expensive for them to run an entire season like that.

Anyway, all I was saying that they're not kids anymore. I think it was the recent announcement of Millie Bobby Brown's marriage that really made me aware of how much time has passed. Season 1 first aired 8 years ago.

That's probably wise. 90's nostalgia seems to be "in" these days.
