An obvious recycled shot of Marshal BraveStarr is used near Stampede's base, with dwellings in the background and terrain that isn't consistent with the ground in the area.
Thirty/Thirty breaks down the door to BraveStarr's sleeping quarters and swings his rifle, Sara Jane while standing in the door opening. As he does so, it appears that Sara Jane is short enough to fit between the door posts while it should have been layered in front of the door instead (animation layer mistake).
