All these comments saying he went back to kill him cause he killed Hank, he went back cause they kept jesse alive and forced him to cook meth, he only went after he found out the blue meth was still around
I like Walter more this way. He always seemed so hesitant doing the dirty stuff during the show. He wasn’t ready for the decisions he made. This time, he was ahead. Be good or be bad. But both sides with all consequences. And if you don’t want to be bad - stay in your classroom teacher.
After years of watching Breaking Bad I just realized that detail , Heisenberg shot Jack while he was still talking, just like Jack did with Hank, poetic justice👏
