Hypochloric acid! WEEE

Matthias frowned. He'd known the girl for less than 10 minutes, and already she was on the floor curled into a terrified screaming ball. He seemed to have that effect on people.
'The Watchers' she'd said. At least three times. What Watchers? Only Watchers Matthias knew of were the ones from Buffy the Vampire Slayer. And, somehow, he doubted she was all that up on the WB Fall lineup.
He stared down at Farrago. She had her eyes tightly shut; she was scowling, tears sliding through her closed eyelids. He winced a little, feeling guilty. Being locked in a dungeon for as long as she had would probably make him more than a bit loopy, too...
"Get up off the floor," he said softly. The normal ringing joy and the cutting anger were both gone from his voice, it was simple, gentle, understanding. "I don't think you're crazy. And I'm damn certain I can fight off the Watchers, whatever they are."
She slowly opened her eyes and looked up at him. "They're already here. They're watching, they're always watching."
"If they do anything, I'll kick their asses back to England."
She shook her head, unsure of what England was. "No, they never do anything, they just watch..."
"Well, then, why do you fear them?"
"They watch!"
"And that's all they do! They won't hurt you. They can't. And if they so much as try..."
Matthias jerked his arm a certain way. It transformed, plates shifting, expanding, and contracting, until it became a huge chaingun barrel. The front spun, not shooting due to the fact it had no ammo. Pulled off the effect, though.
"Now, let's go."
Hesitantly, she rose to her feet. He nodded, and the two of them walked more through the darkened halls, coming ever closer to his stolen sword.
