The Yellow Lantern kept my mouth shut... He obviously couldn't interface with the ring, but to explain why would divulge his weakness.  Yet, it was important information.  "Unfortunately, my ring cannot affect things that are green, nor constructs formed of pure willpower.  By my understanding, a Green Lantern ring is both."  Sinestro said, hoping he hadn't weakened his position too badly.<br/><br/>Yet the newcomer...  he was a fright.  "You've been impaled!" Sinestro shouted, staring at the wound.  With his power ring, he created he yellow floating stretcher.  It had more straps and needles on it than he would like, but it would serve its purpose.  "Come on!  We have to get this man to the medical station.  He's mortally wounded!"  Sinestro said, running towards the bleeding batman.  How was he even still walking?  The girder looked like it had gone clean through his liver.
