The Choad Less Traveled

In Vigilante's car on the dashboard is a figure of Ultra Bunny, a fictional character James Gunn created for The Suicide Squad (2021). Rick Flag wore a T-shirt with Ultra Bunny on it for most of the movie, including when Peacemaker killed him. Vigilante's Ultra Bunny figure can be seen holding an English version of the sign shown on Flag's shirt, which reads "Obstacles are opportunities."

When Harcourt picks Chase up from prison, as he exits the building there's white tape on the latch assembly of the door to ensure it doesn't lock on closing, something which would never be allowed on a prison door but is often used by film crews to ensure the door doesn't lock when the door closes after actors pass through.

After the credits, there is an extra scene from the conversation between Peacemaker (John Cena) and Vigilante (Freddie Stroma) extending upon the phrase "if it walks like a duck."
