Ianto leapt for the sword without a word, or pause for thought. If he had to protect his Captain then he would, it was that simple. Sure, he didn't know much about sword fighting, or using any weapon apart from the clean, efficient gun, but he had to protect Jack. He had to. They were in a different world – who knew what could happen? Maybe in this world Jack could die, maybe in this world he could lose Jack forever. And that thought, which flashed across his mind as he was diving for the blade, was enough to harden his resolve. It wasn't difficult to come to the conclusion that a world without Captain Jack Harkness, was definately not one he wanted to come even close to living in. Unfortunately for Mr. Jones, however, the subject of his thoughts appeared to have the same idea, and no sooner had the coffee-boy laid his hands on the sword, Jack landed ontop of him and began trying to wrestle the weapon away from him.
"Jack, you don't know what'll happen if you die here!"
"Ianto Jones, give me the sword!"
"I can do this!"
"No you can't!"
As the boys fought over their toy, Gwen Cooper sighed explosively, and angrily, and turned to face the enemy with her bare fists, ready to give as good as she got. The intruder, a man (at first appearance), appeared to be a bizarre mix of human and metal. Unlike a cyberman, he reminded her more of Wild Wild West. His chest was coated in an array of finely-wrought metal plates, that curled into somewhat beautiful shapes around the planes of his human torso and up over his collarbone, covering half of his face in a sinister masked-marauder style. Every muscle of her body tensed, she awaited his next move, trying not to fear show on her face. The flesh part of his mouth twitched in a cocky smile as he drew a long, golden blade from a scabbard and flourished it gracefully, ready for battle. Trying to ignore the scuffle behind her, she eyed the villain, daring him to move. He did, and she ducked as the golden blade whizzed lightning-fast over her head, stumbling backwards as a second part of her brain scanned the barn for anything she could use against him. As the razor sharp tip came inches from her eye, and she nearly had a bloody heart attack, the man stopped. She glanced upwards and saw that Jack was triumphantly holding his sword at the metal-man's throat. Another glance spotted Ianto looking furious and flushed, sitting on the floor and glaring at his Captain, reminding Gwen of a peeved cat.
"I will kill you where you stand, soldier, if you take one more step towards her." There was a tense pause before Jack carried on: "I'd advise that you stand down and tell us where the hell we are."
The intruder seemed to contemplate Jack for a moment, though whether he understood the threat was unclear. Fortunately, the nudge of Jack's sword in the flesh of his neck clarified things and he withdrew his weapon, dropping it and raising his hands to show they were empty.
"Better," Affirmed the Captain, "Now who are you and where are we?" The soldier stared moodily at him, not looking like he would back down easily.
