I will retain my gripe about the Cassie time-anamoly thing, and say that while that making her fix the timeline is a neat idea that I don't think she fixes anytime line.
Maybe the Sario Rip in 11 doesn't count as a broken one, but I think of it as such and she didn't fix it.
Moreover, I think it's to do with her time line
I love the way the Ellimist describes life forms as lines in space-time, that he can see where the stretch and grow, but while they connect to many, they are distinct, they start of from a point all their own when one is born, and curl up into nothing when one dies. Cassie's line wouldn't exist in WWII or anything. (Would love to know what happened to it when she went back though)
I see her line as being anchored (grounded, if you will) to table. You can shift it, but you can't pick it up and move it across the room. The lines she's connected with she also anchors, eventually snapping back and bring them with her. Think about the others saw breaks too, but unless they are all somewhat grounded naturally, or it turns out morphing unintentionally does it, a bunch of other people should have been disturbed too, but it only happened to those connected to her, on this issue (avoiding the "Ellimist did" explanation)
But those connections to exist till particular points in time, so she can only effect certain people and events. Just turns out some of those have different scale
