The Big Three Dig Up a Piece of Their Past on This Is Us

As Primetimer's Jessica Liese writes today, we've got a good number of questions we're hoping This is Us will address in its remaining five episodes this season. Tonight's episode, which sees the big three reconnecting at the family cabin, promises to answer at least one of them, as the three siblings unearth the mysterious time capsule Jack buried for them thirty years earlier. Also today: The Conners reopen their beloved restaurant, For Life gets into the groove, Ellen adds a new challenge to her line-up of favorites, and TruTV introduces a new primetime game show structured around the consumption of hot wings. Here's what's new and noteworthy on TV this Tuesday:
