Atalanta startled into action and drew back on her bow, firing shots directly at Herakles, and so did Artemis, but Arash didn't bother to waste time on that and aimed instead for Jason. Almost as though he sensed what was about to happen, Herakles broke off his attack run and spun back around, shattering more of the street as he kicked off the ground and went the complete opposite direction. For an instant, he moved so quickly that I lost sight of him.
And then, like he had teleported, he reappeared in front of Jason, using his body to shield both him and Medea the younger from Arash's volley of arrows. Unlike with Caenis, possessing the Grail did nothing. Arash's arrows still broke uselessly against Herakles' leaden skin, shattering like they were cheap plywood, and then vanishing into particles of light.
