Ways to Become a Hero

Merlin was a hero because he took matters unto himself. When he knew no mortal weapon could kill the wraith he tried to kill it himself and then he found out how to get a sword to defeat it. Dean and Sam take it on themselves to go out and find the dragon and to save the girls. From what we saw in the class they had been unsuccessful in trying to stop whatever the dragons were attempting to do. This just shows that you have to keep working and try again.
