"Sadness" by J. Hunter

The best way to describe this is simply to include the scene from which it came..

*Rusti trusted her senses and crawled cautiously forward.
Oh, if she only had just one simple glimpse of the corridor so
she knew where she was!  Rusti wished she could have counted how
many steps she took from the elevator.  But, she mused, things
like that aren't important when chasing monsters.
     "Ow!" her voice nearly shook the silent world and her ears
hurt from the sound.  But she found him!  Her hands groped,
measuring crevices and corners and sure enough, it was Optimus.
His body was warm to her touch-a good thing.
     Blue light flashed and dimmed as his optics activated.
Rusti found herself face to face with him.  Her touch roused him
either from sleep or unconsciousness. "Russti . . ."  His voice
came so quiet.
     "I'm here!"  She laid both hands on the rim of his helm. Her
heart pattered and she tried to control her anxiety. "Optimus,
are you bleeding?  How can I get help?"
     "Don't . . . leave me."
     The depth of sadness in his voice touch her and Rusti could
not control her tears.  She leaned wearily against him.*
