Milo Ventimiglia, who plays Mandy Moore's late onscreen husband, Jack Pearson, also had a lot to say. "So, that's it," he said on his Instagram story, which he used to give viewers a brief tour of the set, even sharing a few clips of himself and Mandy Moore on their last commute to the set. "That is a wrap on Season 6," he concluded. "That is a wrap on the whole series of 'This is Us.' Thank you for being a part of the journey. Thank you for being around for it all. Hope you've all enjoyed it."
