She might catch sight of a few scars randomly striking over his blue skin. They sort of stick out in dark, or lighter patches, old cuts or bullet wounds, stabs and what could be plenty of surgical scars. There aren't enough to make him ugly, more the opposite, it told a story of a hard, rough life. They were war wounds, badges of honor in some cases... nightmarish memories for others.

If she doesn't look away though she'll get mooned, cause he's stooping over to grab his pants and slip them on. He needed to go to the store to get underwear... ]
