Geoffrey and Kylo seeing and hearing that happen had nothing to say.
Serena also wanted to leave, not wanting to spend more time with Geoffrey, but before she could, he called her name. Left with no choice, she faced him and asked, "Yes?"
Geoffrey turned to look at Kylo signaling him to leave. Kylo took the hint and went on his way. He really didn't want to stay to just feel bad for his cousin. At the end of the day, he's still just a bystander, and whatever he does to interfere will not lead to a good outcome. So, he rather let them sort things out on their own.
When Kylo left, Geoffrey smiled at Serena. "I know it's still early, and you said before that you hate horses, but I still wish to invite you to the polo match on the 5th of May. I can guide you through the rules of the game before my match." He asked earnestly.
"uhm… I heard that my brother Leonard is also playing, so I'm sorry because I'll be rooting for his team." She said honestly.
