I think this is probably closest to her mindset.
But when you see your prophet son crucified what are you to think, has something really gone wrong? How does God get the victory by dying a criminals death? No doubt she, like the Apostles, began to fully figure this out after His resurrection.
Exactly!
Mary is a great example of a devoted mom at the time of the crucifixion. She's also not dissimilar from mom's in general not always understanding, but always concerned. Elevating her beyond that is where the train leaves the tracks.
I think John came the closest to truly understanding before the Resurrection.
I wouldn’t even hazard a guess as to who knew what/the most before the resurrection.
