According to reports, the younger Williams did not show any emotion, nor did she celebrate upon winning the match. Instead, the siblings walked slowly to the net and hugged before walking off the court together. 

"It definitely doesn't get easier," Serena said after her sixth Wimbledon meeting with her sister. "But today I was out there and I just thought, 'Wow, I'm 33, and she just turned 35, I don't know how many more moments like this we'll have.'

"I plan on playing for years but you never know if we'll have the opportunity to face each other," she added. "I just took the moment in and I thought, 'We're at Wimbledon.' I remember when I was 8 years old, we dreamed of this moment and it was kind of surreal for a minute there."
