James couldn't believe what he was hearing. It wasn't like he didn't expect it, but to actually hear it was a different story. He felt himself gaping at Sirius, disbelief and hurt written all over his face. He quickly covered it up with an angry expression at the vile things that he was saying. Before he could stop himself, he gave in to his anger and yelled out after Sirius:
"Get on then, before I hex your dumb arse!" With a barely contained growl, he turned back to the Gryffindors gathered about, passing them all a hot look.
"Just forget his buggering arse. He's being a prat. This isn't about stupid hexes that won't do anything serious," he insisted. "I mean real spells, defensive magic that won't just trip someone up, but keep them immobilised or disarm them. That's the real trick." James felt himself brightening in mood as he spoke, tackling an area that he knew how to handle.
