Meester has said, in the Porter magazine interview in 2018, that Gossip Girl placed her in a specific vulnerability: “I was young when I started Gossip Girl. A lot more people were suddenly around and I was being looked at.” She has described the transition from working actress to recognizable star as something that required her to figure out quickly who she was and what she was about, with less time and less cognitive development to draw on than the situation required. She was lucky, she has said, to find and keep friends who were genuinely loyal rather than interested primarily in her celebrity. That luck — and her ability to recognize the difference between the two categories of people — appears to have been the primary protection available to her during those years.
Before Gossip Girl, she was a recognizable type in the television industry: the capable young actress who shows up, does good work, and departs. She had not yet been the lead of anything. She had not yet carried a show. The skills she was developing were the skills of a working professional in the supporting tier of her industry — real skills, genuinely useful, but not yet expressed in any role substantial enough to define what she was capable of.
