Yes, he'd connected! Justice didn't even care that splatters of Regan's blood had dripped down onto him, although he'd want to shower as soon as he was done here. He had no interest in walking around with dirty foreign blood smeared on him. He pulled harder at the hair wrapped around his fist, hoping to distract his opponent if he could. Justice was a dirty fighter, and he didn't give a shit what anyone thought of his tactics.
Regan's flying fist caught him in the eye, and he made a guttural, roaring sound at the burning pain that caused but shook it off soon enough. He took the next hit right in the jaw and let go of the other man's hair in favor of using both arms for leverage to sit up as well as he could, thrusting his head forward, the intent to bang his forehead against Regan's and hopefully stun the man enough to get him off of him.
