The moment Serena tried to be stubborn yet again and refuse to stay behind, Kay foiund herself yet again pinching the bridge of her nose as she exhaled in frustration. She was glad that John and Bane both told her no because she herself was not in the mood to fight Serena verbally all over again over this situation. 

She looked up at Bane and nodded, "right" she replied. "Go, just come back safe and sound and I'll look after these two" Sam told her before letting them both leave, which they did. Kay lead the way out of the house and toyed with the idea of taking the car, but she also didn't want to risk damaging it as it was a hire.
