"Ah might be able to keep one of those guns occupied," Sam drawled as he listened to Jeb mention that the pirate ship could shoot back. Grinning as he flew and cut his speed to match the pirate vessel, he expanded his field into a decent sized bubble around him as the shells hit.
Sam knew using his field like that made him less aerodynamic, but it also gave a nice area that the enemy gun couldn't help but hit as it fired at the Zebulon. He might not be able to block all the enemy weapons, but he'd at least cut the odds of the Zeb taking fire.
Plus he figured soaking up that kinetic impact from the weapons fire might come in handy once the enemy ship crashed.
