THEORY Why doesn't Garu speak? Tobe's revenge?

 

1 DATA, 1 MINUTE this is the question that everyone has asked why Garu does not speak? the answer is ..... you have to see two chapters or videos to understand,

the first is "the true reasons of garu" and the other is called "my beloved clone"

in the real garo reasons we see something disturbing. Garu's father was killed by apparently tobe or Tobe's father, and in my beloved clone we see that when Garu became a ninja he swore that he would never speak again. He apparently means that Garu killed Tobe's father and that is why Tobe wants Revenge. Thanks
