- "I'm making a list of everything I want to keep about the world, you know, when the war's over. And, uh, everything I think we should get rid of. (...) Well, we're gonna lose dictators, keep democracy. Lose weapons people use on each other and keep weapons to use on aliens. Uh, lose anything jerky or anything pickled. Keep anything chocolate-covered."

Matt asks why they are leaving, and his dad tells him that they are going someplace better. Matt, saddened by this, says its the 8th and asks about his birthday party that was supposed to be tonight. His oldest brother, Hal, jokes around saying take it easy your highness, stinging Matt into a response, saying Hal had a birthday party, and it was after the invasion. Tom reassures his son that they'll do something when they get settled, which mollifies him, as the 2nd Mass begins to move out.
Later, after scavenging what's left in a grocery store, Matt worriedly asks his dad repeatedly if he'll be at the meet up location; as Tom volunteered to go back to find supplies. Hal tells him to give it a rest, while Tom continues to reassure him that he will be there. Matt tells him he already knows what he is gong to wish for. Tom inquires what it is, and Matt is hesitant at first, but caves saying he wishes everything would go back to normal, including having his mom and Ben back. His dad hugs him and tells him he wishes that too, and reassures him that it will get better. Hal then offers a high five, but quickly dodges it saying too slow. However Matt quickly high fives his other hand saying Hal's the one who is slow, before moving out with the rest of the civilians.

Against Maggie's objections, Matt insists on taking her back to base where Colonel Weaver wants to kill her, believing her to be another Espheni clone. Matt convinces Weaver to spare her until Tom returns and she is instead locked up. Matt is upset by Hal's reaction to Alexis' return and stalks off. When John Pope attacks, Matt takes part in the fight and later apologizes for brining Alexis to the base as it turns out she was just a clone sent to assassinate Tom. Tom forgives his son, telling him that thanks to Matt bringing the Alexis clone back, they now have a major piece of the puzzle. Matt watches as Tom starts to broadcast to the other militias before a massive swarm of Black Hornets appears headed straight for the base.
Months after the war has ended, Matt is seen recapping the last battle, recording the information in a book.
Tom decides to use service tunnels to sneak a strike team into the city rather than a full-out assault on the Lincoln Memorial. Matt joins the strike team, and tells JickJack not to touch the Espheni egg. Maggie pulls Matt back, and watches as the Espheni bursts out of the egg and explodes through JickJack's stomach. Matt takes cover when Lt. Demarcus Wolf shoots an explosive at a nest of baby Overlords. As the group is trapped, Tom continues on his mission to kill the Espheni Queen. Matt is present when Anne Mason dies, after being hit by shrapnel, and is shown to be in tears. Matt watches as Tom arrives, then takes Anne off to be resurrected by the Dornia. As Tom killed the Queen before arriving, all Espheni forces are destroyed.
Matt begins to play a tape of Evelyn singing while he writes his book. As Matt looks at the time, he discovers that he's late, blows out the candles and shuts the book, revealing the title to be "Last of the World War", by Matthew Spencer Mason. Matt gives his father the book, and Tom is proud of him for writing it, always saying during the invasion that someone will have to record what happened for history. Tom asks Matt if he'd like to be secretary of state, however Matt denies saying he has a date, being Evelyn. Matt tells his father that this book might make them ask Tom to be president again. Matt tells his father just to give a good speech. Matt leaves and when Daniel Weaver approaches, Matt salutes, then immediately hugs him. During Tom's speech, Matt is next to Tom along with the important figures of the 2nd Mass.
