Jack Barnes has a few minor skirmishes under his belt, but for all his bluster about them you’d think that he’s lived through several world wars!
He’s cocky and arrogant and enjoys re-enacting tales of previous “glories” to the rather gullible Tom. He is a typical lad’s lad and because he’s slightly superior to the Privates he bullies them a little.
However despite all his bravado when it comes to the heat of battle he is a coward.
He is 27 years old and his likeness is based on Justin Chambers, aka Alex Karev in Grey's Anatomy.
