After "This Is Us" Season 3's brief hiatus to give way to the midterm elections, the show will return with a lot of surprises. Episode 7, titled "Sometimes," will show Jack (Milo Ventimiglia) and Rebecca's (Mandy Moore) sweet moments together while the season may reveal Kate (Chrissy Metz) and Toby's (Chris Sullivan) heartbreaking storyline.

In an interview with Entertainment Weekly, Chrissy Metz revealed that an upcoming Kate and Toby's storyline on "This Is Us" Season 3 would be a "first on network television." "Toby and Kate are going to have a bit of an unconventional parenting situation," she said.

After a miscarriage and some attempts to get pregnant, Kate and Toby sought the help of IVF. Chrissy Metz's character, fortunately, got pregnant, but they are once again up for a big challenge in "This Is Us" Season 3. It is something fans have never seen before.

Chrissy Metz explained that the challenge they are going to face in "This Is Us" Season 3 is something that Kate and Toby have never thought of.  The said storyline is also going to be a big challenge for the 38-year-old star as an actress that makes her both excited and scared.

On the other hand, executive producer Elizabeth Berger teased that fans are going to see "very specific struggles" that Kate and Toby have to face in "This Is Us" Season 3. "It's not necessarily something that we've seen up close before," she added.

There are theories that Kate and Toby may call it quits in "This Is Us" Season 3 after a flash-forward scene showed Chris Sullivan's character not wearing his wedding ring. He is also struggling after he stops taking his anti-depressants. Will it happen this season?

Meanwhile, in "This Is Us" Season 3 Episode 7 "Sometimes" return, fans are about to see the earlier stage of Jack and Rebecca's relationship. According to TV Insider, in the newly revealed promotional images, the couple enjoys a road trip going to Los Angeles. From the looks of it, they are still on the stage of getting to know each other.

Viewers will also see Kevin (Justin Hartley) and Zoe (Melanie Liburd) having a trip of their own in Vietnam. The show will also give another look to Jack's brother, Nicky (Michael Angarano), and his war story. "This Is Us" Season 3 Episode 7 "Sometimes" will hit the small screens on Tuesday, November 13, on NBC.
