Apollo laughed, "Seriously?" He swatted Castor as he moved to the side allowing him to greet the little nymph. Satisfied that he could focus all his attentions somewhere else, Apollo turned to Pollux- throwing one arm around the other. "Why yes, that would be a good start. And then a drink might make it all perfect."
"Come on, I think we can leave your brother to nymph-sit for a bit while we get something from the bar." Eager and curious (because this was an experiment of course- he was looking forward to seeing how this would turn out. Not just here now, but later if a certain goat-faced god showed up. If.)
Syrinx had taken a rather significant step back when Castor circumvented Apollo to come greet her. Rather apprehensive at this, she clasped her hands in front of her, fingers tangling and untangling- grasping and letting go.
Castor.
Her mouth opened a little in a soundless 'Oooh', comprehension dawning in those deer-like eyes and she smiled up at him in greeting.
