Title: Flexibility, Love, and Trust; or, Blind Dates Are No Day At The Beach
Luke strolled along the boardwalk, appreciating the fragrant sea air. The beach was a lot less crowded than he'd expected for a holiday town at the height of summer, but that suited him fine. He bought some fries and walked idly on, listening to the calls of a carnival barker, the vibrant medley of beeps and bells leaking from a video arcade, the shrieks and whoops coming from thrill rides. It all washed together into a kind of music.
He did notice as he passed a little green girl wearing a bow tie. He was supposed to be looking for a woman in a red bow tie, an older woman - wait, a *green* girl? She watched him watching her, assessing him coldly for a bare few seconds, then approached. "Good afternoon, human gentleman," she declared in an artificially cheery tone. Luke could see the wariness in her eyes, behind green-tinted glasses. "I wonder if you've seen a bold young human warrior, a masterful wielder of unknown powers. His name is Sky Walking, though based on what I know of Beach City names it seems like some sort of alias." She waited imperiously for a response.
Luke smiled, his eyes twinkling over a tidy grey beard, recently trimmed and shaped. "I suppose you might be Peridot, then?" The girl's eyes widened. "I thought Terra's population was almost exclusively human."
Skepticism fought disdain across her face. "Sky Walking? You look a lot less... muscular than I imagined."
"It's Skywalker, actually, but Luke is just fine with me." He sighed. "I guess Steven wasn't very specific with either of us when he set this date up."
Peridot began to relax a little. "He does get a little. Very. Enthusiastic about his friends. And making his friends make friends." She stopped. "Wait, what's a date?"
