[Didn't see him? Didn't see HIM? What the hell did they mean, didn't see him? Okay, that's it...Ed takes a deep breath and shouts quite passionately...]
WHO'RE YOU CALLING SO SHORT YOU CAN'T SEE HIM IN THE DARK WITHOUT A STUPID LIGHT? I'LL GIVE YOU A FIST IN THE FACE FOR THAT!
[Yep, you've riled Ed up enough to send the alchemist launching himself into the fight. Granted, he's aware that his alchemy tires him out here more than ever. But, at least in this case, he can still transmute his automail arm into a sword. He claps his hands, causing a brief beam of light, and his arm changes into a dagger point. He uses this to launch himself forward at the strange guy, clearly not caring that he was getting involved into someone else's fight at that moment.]
