No One Will Harm You

La Cosa has inexplicably joined El Hombre Topo:

"Benjamin, I heard voices!  Who are you talking to?" 
 "The Moleman!" 

"My greatest enemies!" 
 "Easy, nothing's wrong!  You don't have to worry!  No one will do you harm while I'm here!"

Notes:
mayor could mean either great, or old.  I translated it as the former.
hacer daño is literally to make damage.
