This immunity has then been referenced several times, when a convoluted plot device saved Bob or George's life in a seemingly hopeless situation. In the comic of March 18, 2004 however, George was actually killed in battle. The Author then later brought him back to life, showing that title characters can be killed, just not permanently unless The Author is first taken care of. As George temporary died at one time, it appears that title characters aren't really very much different from the rest of the main cast, of which none have permamently died.
