Her shoulders slump.] It wasn't your fault. Dipper and I never should have taken the risk. Wirt warned us what would happen, and he was right.

[so really the fault lies with her and Dipper. they both know that and they both made peace with that. and somehow in all of that, it didn't occur to her that their foolishness got Stan and Ford killed too.]
