Intentionality and temporal wedgies

So, the second part of the series close-out for Gravity Falls is up and it's pretty much what I sort of expected: Mabel has no real idea that anything abnormal is happening nor does she really quite remember what touched off the latest weird thing. While she says that she passed out in Sweater Land and woke up in her bubble, she probably does vaguely remember talking to Blendin Blandin about some vague thing. This makes her that staple of fiction, the unwitting instigator of doom. She has no idea what she did wrong and everyone wants to follow Dipper's lead and keep her from finding out because it might do more harm than good to tell her. This, I think, is akin to how it's not a smart idea to blame the character April Patterson from the comic strip "For Better Or For Worse" for the death of their dog after he rescued her from drowning. She had no idea that the river was in flood stage because no one told her or was looking out for her.

Contrast Mabel with Starlight Glimmer who is about to deliberately screw over everyone ever just to prove that her stupid, unworkable and ultimately mean-spirited attempt to 'save' the world and coincidentally make her feel like she matters is tenable. The end result is to see her punished for damages yet to be unspecified by forcing her to give up her powers until such time as her jailer Twilight Sparkle sees fir to return them. This is necessary because she knows what she's doing and why.
