Tuesday's episode is a return to "classic This Is Us"

Entertainment Weekly

“It’s old-school in the best way. Old-school This Is Us,” executive producer Isaac Aptaker tells EW of tonight's episode, adding: “We knew we wanted to take a really big swing with our season premiere and introduce all of these new characters — and in a way, do something reminiscent of the pilot where there was a big twist at the end as to how everything connects. But we also know how much people love the Pearsons and the Big Three in our regular cast. So it was always probably the plan to have the next episode be a real return to form for us. And we’re doing that in a very big way.”
