Sylar doesn't like to run away, because it admits defeat, but he will if he has to.

But hey, if the people who tried to make him dead again want to give him another excuse to be violent towards them, then to a great extent he's really not complaining.

This body might be tired, but it's large and it's strong. Dean's tackle does knock him off-balance; he keeps at least one foot free and aims a fierce kick at the man's face. But he's falling as he does, and making a grab for Jo's arms, partly to deflect her attack and partly to either stop himself from falling or bring her down with him.
