Not only is she Owen’s ex.

“We picked back up where we left off,” Lowe tells EW of the reunion.

“I’m so glad we could because the pandemic has helped in some ways.

It’s fun to come in and discover that things have changed over the last couple of months.

She and Rob are so great together.

The chemistry is there.”

“But I do think they both sort of tick each other’s fantasy box.

So there’s some real-life role-playing going on in their relationship.

Nonetheless, Minear seems optimistic when it comes to this pairing.

“For Owen, this was the deepest, most perfect relationship of his life,” he says.

It’s really great for him.

There will be complications because it’s not like she was in cryogenic freeze for years.

She’s had a whole life so we’ll discover a little bit about that too.”

Gwyneth’s not the only new face in town.

“Gina is a goddess,” says Minear.

“She plays a character who has been out of the workforce for the last eight years.

She’s been raising these girls and she’s been loving life.

Her husband is a restauranteur and his restaurant has gone under because of COVID.

So they’ve lost their business.

So she was forced to return to the workforce.

That’s very relatable for a lot of people right now.”

Her first day, it felt like she’d been on the show since the beginning."
