Riverdaleis the oldest its been, and yet the characters haven’t aged a day.

Or more accurately, the characters did age… but then the show went back in time.

Not only that, but the former young adults are teenagers again, back in high school.

“Not in a bad way, but none of us look like we’re 17.

But it’s been fun to lean into the innocence.

“It’s going back to our roots, in a sense.

It’s this young, fiery, curious Betty.

A new side of Betty also comes with a new side of Barchie.

Fans will once again get to watch the friends (and neighbors) contemplate becoming something more.

We just shot a scene yesterday and he made me cry because of how good he was in it.

The Barchie of it all is definitely full circle.

We shot a scene in front of Betty’s house the other day.

There’s a lot of sweet, nostalgic moments throughout the last season.”

One other nostalgic thing that will be making a return (at least in one episode)?

“You do see the pony,” Reinhart says, despite her shorter hair.

“I do have a pony in episode 5.”
