Class with movie clip actions

ok, i use addChild to load a character (MC) from the library and take actions, if i reffer to the MC the new caracter loads into i can get simple direction control, only because the child is attached to the parent, but when i try to do somthing like a goto command it will not work,

the simple script

player.addChild(new emilia);
trace(emilia); // output = [class emilia]
trace(player); // output = [object MovieClip]
player.x = 200;
player.y = 490;
emilia.gotoAndStop("duck");

is there a way for me to be able to load in “emilia” as its own MC to be able to receive time line controls?
