Sarah Michelle Gellar is mourning the loss of her ‘Buffy’ castmate Nicholas Brendon, who died of natural causes at age 54. Quoting his character, Xander Harris, she wrote: “They'll never know how tough it is … to live so near the spotlight and never step in it. But I know. I see more than anybody realizes because nobody's watching me.” Added Sarah Michelle, 48: “I saw you, Nicky. I know you are at peace, in that big rocking chair in the sky” 🤍 #buffy #rip 📸: sarahmgellar
