Oh, no. Cappi didn't attack Cotan. :) Cappi started the acrobatics to avoid further incoming vines and pebbles. That's why he said try again. Like, try what you just did, again.
But if Cotan ran headlong into Cappi's activity and engaged him rather than trying more telekinetic 'attacs', then the result would be exactly what you posted. So I leave you with the option to edit or not.
Hey we're still waiting on your post on the Krayt Dragon and the Mynock! Please get it in as soon as possible, or if you're having difficulty with RL or thread overload just let me or Undine know! We'll figure something out as to why you're 'late' to the class.
