it was never burnt up. it was just simply abandoned and probably trashed.bruh, when Walt went back, the house was all burned up . . Jessie definitely set fire to that bitchThe house clearly doesn't burn down, cause Walt returned to it in the first episode of this season. If Walt Jr. is home, I think he'll catch Jesse, and Jesse will take off. In the preview for next week's episode you hear Walt Jr. say something like "no more lies".
