The 11th Doctor was looking at him. He seemed to focused on the Daleks. He had hoped the sound would distract them or throw off thier focus. He seemed to be thinking of another plan. He knew that they would destroy his first self to destroy him.
"I don't need weapons." he replied. The 11t Doctor sounded confident about that, Eleven was looking around. He needed something he could damage that would hurt the Dalekes. He see's a barrel of gas and seems to smirk.

"I have my ways." Was all Eleven said. He glared at them , he pointed to the barrel of gas with his sonic screwdriver "Back off or I blow it up." There was a serious look in his eyes. He planned to blow it up regaurdless.
The time lord hoped he could get them to back away from One.
