When Toby and Malik take the detonators from Madison, Malik holds his detonator in his right hand and Toby holds his detonator in his left hand. After they both push the button to blow up Madison, the shot switches to show them from behind ducking away from the explosion. During this shot Toby is now holding his detonator in the opposite hand than just a split second before.
When Toby and Malik leave the gravel pit the shadows are long indicating it is late evening. Later, as Toby and Malik stop, while Toby explains why those guys are after him, the shadows are much shorter.
