“Slipped”? Nonsense. At the time of the photo she is being helped by two persons who have her arms. This is not the aftermath of a slip - look at the distance of the man on her right, and his composure. He’s not rushing to catch her. He’s been helping her for several steps, at least. Likewise with the man on her left, completely composed. She was being assisted up the steps, she didn’t slip.
And check out the pic of them lower down on the steps, the people at each side are closer, and have their arms under hers in the “guide the frail elder” position.
She needed help all the way up those stairs.
And then right after, the press was forbidden to show her going up the stairs to her plane.
Something’s up, and they were being told to hide it.
It it being brought to the light of day, though.
