Toby spends some alone time with baby Jack while Kate goes off to meet with her brothers on This Is Us. "The Cabin" is the 14th episode of the show's fourth season.
Rebecca: How long have I been out? Jack: Just a few minutes. Rebecca: Great third date. Isn't it crazy? A few weeks ago I was in a bar looking at a cute guy -- not you, you came later. But isn't it weird how meeting someone can change everything?
