Relena saw Heero standing alone on the street corner looking out over a bridge. His head was bowed against the sea breeze and his jacket flapped at his sides like a dark cloak. She turned her head. No sign of anyone else, student, teacher, pilot or other was within this immediate vicinity and she smiled smugly to herself. Feeling confident, Relena strode up along side him and leaned against the railing to get a better look at him and make her presence known. Her eyes fell over every delectable inch of him from his gorgeous face to the strong muscles under the loose green tank top. Her eyes stopped suddenly as they came upon a large bulge in the front of his revealing spandex shorts. With a deepening blush she leaned forward, her lips grazing his skin as she whispered, "Is that a gun in your pocket or are you just happy to see me?"
He turned towards her, eyes narrowed, "It's a gun."

Also, have you ever noticed that in episode three of GW that when they show the body schematics of Heero.. he.. um...is lacking something of rather great importance..? That is to say... his.. uh... ::blush:: ANYWAY.....

"As you can see, despite the fact that he is decidable male, we have no proof." Sally Po said while explaining the physicality of the strong.. er.. boy brought in that morning. Heero seemed rather pissed, Relena was a bit distraught while Duo seemed to find great humor in the situation. Heero later took apart the baka's gundam. Revenge well served. As for Sally, she became convinced Heero's brain might actuality be located in his head in contrast to its location in most men and did her best to aid in his defense. Relena, on the other hand, assured herself modern science had come a long way and still has high hopes. Damn.
