Stephen goes to the lecture with Elaine, the two having fallen in love. At the same time, Jane and Jonathan reunite. While at his lecture in America, Stephen sees a student in the front of the room drop a pen from her desk. He imagines himself getting up to return it, almost crying at the reminder of how his disease has affected him. However, he presses on, and gives an inspiring speech about human endeavour. Soon after, Jane receives a letter from Stephen inviting her to meet the Queen with him. Jane and Stephen reunite as they meet her, the two happily talking in the courtyard. Stephen and Jane look out to see their children playing, Stephen joyfully saying "look what we made" in a reference to Jane's old wish to stick by him.
In a final scene, the film rewinds to the moment Stephen and Jane first met, mirroring Stephen's wish to reverse time to see what happened at the beginning of the universe. The closing text states that Jane and Jonathan later married, and that Jane and Stephen remain close friends to this day.
