So I broke the game

On entry to the companions guild kodak asks vilkas to test your arm, once we got out back and he drew his blade i proceeded to us frost cloak and frost bite on him. After I realized he wouldn't count that i stopped but I was too late, now he is standing there screaming WHAT WHAT WHAT WHAT while drawing and putting his sword away repeatedly. Any suggestions? Tried waiting and the situation hasn't changed

edit: Used calm to shut him up and he allowed me to join the companions finally
