(NBC) — It’s getting real for fans of NBC’s “This Is Us” and the show is down to its final four episodes.

Tuesday’s episode focuses heavily on the character of Miguel, played by actor Jon Huertas, and his relationship over the years with the Pearson family, first as a friend and then eventually as a widowed Rebecca’s (Mandy Moore) new husband.

For Huertas, the episode is a chance to add even more layers to his character.

“What I’m really excited to see is how the audience realizes, maybe at the end of the season, what Miguel might have meant to the Pearson family,” said Huertas. “And we kinda know what he means to Rebecca, but I think to go deeper is great.”

“This Is Us” airs Tuesday at 9 p.m., followed by a new episode of “New Amsterdam.”

The series finale will air Tuesday, May 24.

Brown) searching for love and fulfillment in the present day along with Toby (Chris Sullivan) and Beth (Susan Kelechi Watson).
