Ash took a step forward in an attempt to help Chaz, but once the transformation started there was nothing he could do to help anymore. He took a couple steps back, finding Jon with his hand and gripping fingers into the thick fur at his scruff for his own comfort.
His change was starting to happen, but he still stubbornly and painfully held it back as long as he could. He was going to see Chaz through his transformation as he promised.
A gasp fell from his lips and fur sprouted through his skin and then another cry as bones twisted so sharply it brought him to his knees. He couldn't hold back anymore, the urge was too intense and with a cry that melted into a howl he finally gave in and let the moon have him.
