Edwin states that “you can never heal completely until you discover one thing” but does not tell Cole what that thing is. What do you think Edwin is referring to?

He doesn't say in the chapter. I think it has to do with perspective and attitude. Cole could use the knife to help or hurt himself.

it more about your personal thought into it. there is reading and referring to do with this. and OMG aslan how come you answered like all the questions!!

I think it has to do with the rock hidden under the underground caves, later on in chapter 27.

he is refring to the bear
