Since he came before the drake in initiative order, could Angus do something before getting dusted?

The drake was holding its action until its command was given. But I would say Angus could give some warning or something as he would be on guard when he heard the draconic command to attack Angus and probably just heard it move  which allowed him to dodge the initial bite that broke the Drake's invisibility.
