Vayne was no fool. Seeing Ezreal in full retreat, she immediately gave up the chase, and turned instead to Jarvan and Riven.
Of course, even Shallow Dream had been startled! Not even she had been able to detect him before he was already right on top of Orianna.
What if he'd used that sneaky, unfathomable assassination technique of his on the ADC, who'd been likewise occupied at the time?
The ADC champion is constantly being threatened by the enemy front-liners. If she'd somehow been caught by CC for a moment, and Ezreal attacked her with Muramana and Infinity Edge in either hand, she'd have been instantly deleted with no chance to respond!
With Orianna out of play for the time being, Vayne was now the sole damage-dealer on blue team. Sona, Lee Sin, and Shen only had limited offensive capabilities—not to mention that Shen now had to extract himself from the enemy team's midst, after which his main priority would be ensuring Vayne's safety.
