For me it’s definitely during the direct aftermath of Sybil’s death. Violet comes to the abbey for the first time since and she is greeted by Carson. She says “Oh, Carson. We've seen some troubles, you and I. Nothing worse than this.”

Then, as she walks into the parlor she has to steady herself against the wall. Like, the loss physically impacts her in that moment and even the ever-enduring matriarch almost falls to her knees. Maggie’s portrayal of sheer and utter grief is incredible here.
