It was okay that he cut him off at three, really it was, because Raph was planning on attacking right before two anyway. Which he did, careful to dodge out of the way the man was shooting in the near-dark.

He couldn't let him gain an advantage by getting into a darker place in the woods, though, or else they wouldn't be able to see each other. If he couldn't see the guy, he might luck out and a wild shot might actually hit him.

Kicking a branch into some bushes to make a rustle in a direction he wasn't attacking from, be he leaped out through some bushes (that camouflage training in the woods outside the farmhouse? so worth the investment) and attacked, using his sais to try to twist the shotgun out of Dean's hands.
