Jack forces Miguel and Rebecca to 'get to know each other' in This Is Us clip

Meet Miguel. Best friend of Jack. Husband of Rebecca. Sure, you think you know him, but there is much to learn before the end of the series.

Tuesday's episode of This Is Us, which is the fourth-to-last-ever installment of the hit family drama, will delve into the life story of Miguel (Jon Huertas), dating back to when he was just a kid playing baseball in Puerto Rico. You'll see him move with his family to Pennsylvania and find struggles, success, and heartbreak along the way. You'll also see a fuller picture of his relationship with Rebecca, including illumination on how they reunited, this time romantically. "Informative," "bountiful," and "realized" is how Huertas describes this deep dive.

In this exclusive clip from "Miguel," we're whisking you back to a simpler time: the '70s. Miguel has a shiny new El Camino, and his best buddy, Jack (Milo Ventimiglia), really wants him to spend time with his new girlfriend, Rebecca (Mandy Moore). But there's one problem: Rebecca does not appear to be a fan of Miguel, and she definitely does not enjoy his jokes. Can he turn it around and win her over? Er, we're talking about just as friends. At least for the next few decades.

"Miguel" airs Tuesday at 9 p.m. ET/PT on NBC.
