Peacemaker draws an upside down dove on a .50 caliber gun with a Sharpie, with the beak facing to the left. The next shot shows a dove drawn differently with the beak facing right.
A 50 caliber bullet would've gone right through "Mama Bear" and struck "Papa Bear" and probably gone through him too.
When Peacemaker and Harcourt are outside Senator Goff's home, fireflies can be seen. There are no fireflies that produce light in Washington State.
