When Vivienne walked out of the store, they recognised 2 guys in striped/black suits.
Vivienne already noticed their suspisious behaviour and decided to keep an eye on them.
When Vivienne confirmed that the 2 guys were following them.
Vivienne started to run,
They ran themselves stuck in an alley.
When the men jumped around the corner a war had begun.
The smoke pulled away, what the 2 men found was a filtrated body bleeding on the ground.
Vivienne had been wasted.
