Jason is a shapeshifter but...he has time to grow into himself. There is no rush, after all, for a shifter to uncover their shifted form, their true form, but he has a feeling that he already knows exactly what he is going to transform into.
And that is why he stands in the mountains, the wind licking at his skin, brushing his hair softly back from his face. He is right where he needs to be, the first tingles of his first shift flowing over him. He pants and grunts, bones crackling, skin bubbling, transformation swelling through his body as arousal flickers.
For the mere act of transformation can be intoxicating in its arousal too and that is something very, very new to Jason...
