Lucy Preston, Wyatt Logan and Rufus Carlin track Garcia Flynn to the night of Abraham Lincoln's assassination, where he has joined up with John Wilkes Booth; the team debates whether they should alter history.
The episode opens on the evening of April 14th, 1865. John Wilkes Booth is sitting in a bar listening to Lincoln's bodyguard talking about how Lincoln doesn't want protection tonight. Booth walks out of the bar into Ford's Theater next door. Inside the theater, Abraham Lincoln, his wife, General Henry Rathbone, and Clara Harris are watching the play Our American Cousin. When actor Harry Hawk is alone on stage, Booth enters the president's box and shoots Lincoln from behind. After a struggle with Rathbone, Booth jumps down to the stage and shouts his famous line: "Sic semper tyrannis! The South shall be free!" before running offstage.
- Provide John Wilkes Booth and his co-conspirators with semi-automatic weapons to assassinate not only Abraham Lincoln, but also Vice President Andrew Johnson, Secretary of State William H. Seward, and General Ulysses S. Grant on the same night.
- Remember that Booth's original plan was to effectively decapitate the leaders of the Union, not just Lincoln.
Changes to the Timeline
- Lincoln's assassin is Flynn, who is not identified by the press. However, the assassination is still traced to Booth, who is still hunted down and killed in the corrected timeline.
- Because Lucy, a.k.a. Juliet Shakesman, saves Grant from Flynn, a high school in Grant's hometown of Point Pleasant, Ohio, is named after her.
