The latest issue of Empire Magazine has an awesome feature on Jon Bernthal's Punisher from Daredevil season two, and among their revealing chat with the actor is a lengthy description of a scene which takes place between Frank Castle and The Man Without Fear at a fairly late stage in the season. Shockingly, it sounds like these two may at some point put their differences aside after clashing.
The actor playing Man Justifiably Terrified By The Punisher wrenches open the door and limps through the cabin into his chambers. After a beat, Bernthal - assault rifle in the ready position - follows. Gunfire is exchanged, and the scene ends with The Punisher standing over the man as he begs for his life. Bernthal takes out a handgun anf puts it in the man's mouth. Lost in character, Bernthal calls the man a "cocksucker."
And then, just as Frank is about to Castle the poor chap, in barges Charlie Cox as that do-gooding Daredevil. "GET OUTTA HERE RED!" yells Bernthal, a line which tells us that, though their methods are different, The Punisher and Daredevil have formed an alliance of sorts. What happens next - Castle leaping up and pushing Daredevil out of the room - tells us that alliance is fairly brittle.
