You know what? Morgana was seen making a run for it while killing knights that got in her way. Later on, though, she suddenly returns to fight Gwen, which was really surprising, since she was injured and unable to use magic. What I think is, she got her magic back by going to her bedroom to remove the poppet but refused to fight Gwen with it, since she could easily defeat her with a sword as well. Which means, she may have teleported out of Camelot due to her own magic, since she had removed the poppet. Alternatively, since Merlin was seen concentrating to be able to prevent Morgana from using magic, maybe using a stunning spell AND concentrating his powers at the same time isn't possible, even for someone like him.
