- Thompson exits to set his bomb, but it is deactivated just in time by Samberly. Thompson resets the bomb just when Wilkes, convinced by Carter to do the right thing, confronts Frost. Jason Wilkes expels the Zero Matter within him in a violent explosion that is felt by Peggy Carter, Daniel Sousa, Aloysius Samberly, and Jack Thompson.
- The group finds Wilkes alive, but discovers Whitney Frost absorbing the black substance into herself. Everyone flees as her power increases. As Frost pursues, she gets hit by a car driven by Edwin Jarvis and Howard Stark. Everyone gets inside Stark and Samberly's cars as Frost stands and frowns.

- News from August 1945
- In an extended scene from The Incredible Hulk, General Ross says he was 27 when he came home from Vietnam.
Working back from the dates that The Incredible Hulk and Captain America: Civil War are set and William Hurt's age when he filmed both, then taking a weighted average, Ross would have been born around 1952.
However, this would put his return around 1979. The last American troops withdrew from Vietnam in March 1973, so it can be assumed that Ross withdrew with the last of them and no earlier.
If he was 27 in March 1973, that means he was born around September 1945.

- In The Iron Ceiling, Carter translates a coded message saying a deal will occur on "April 27th," to which Thompson replies , "That's less than two days from now." The season is in 1946, a year after Rogers' disappearance in March 1945, and approaching the first anniversary of V-E Day on May 8, 1945 (seen in Valediction). This places that on April 25, 1946, and the events of Now is Not the End to The Iron Ceiling revolve around that date.

However, Carter is shocked, as that paper has been written a day early, with July 15th being tomorrow. This places that on July 14, 1947. This also fits with the date shown in The Good Samaritan of a letter sent on the discovery of Zero Matter as July 13, 1947, and the fact that Jarvis' will, written before Monsters, was written on "July 9, 1947." The events of Agent Carter: Season 2 revolve around the July 14, 1947 date.

- In Hollywood Ending, Daniel Sousa and Peggy Carter are last shown on July 27, 1947 (see other references) beginning a relationship. In Avengers: Endgame, on June 27, 1949 (see other references), Peggy Carter is shown to be single. In Alien Commies from the Future!, Sousa and Carter's breakup is alluded to when, in 1955, Daisy Johnson sees his file and knows from the history of the main timeline that by that point he is "Peggy Carter's old partner", and then in that episode and Out of the Past Sousa referencing Carter being in his past and his breakup in a timeline that at that point is supposed to be near-identical to the main timeline. So, Sousa and Carter break up between July 27, 1947 and June 27, 1949. Using the midpoint of this period as an approximation, it can be taken to have been July 12, 1948.

- Christopher Markus says Steve Rogers went back in time to "roughly '48". Stephen McFeely says "1948", sometime after the second season of Agent Carter (which finishes in July 1947 (see other references)). However, the film's shooting script, written by them, explicitly says "1949", and that Rogers is "112" (biologically). Rogers is biologically 38.7 at the time of his time travel, so lived a further 73.3-74.3 years back to October 30, 2023 (see 2023 references), meaning he arrived back in time between approximately June 27, 1949 and June 26, 1950. Assuming the earliest possible, to be as close as possible to the "1948" comments, Rogers can be taken to have traveled to June 27, 1949.
