“When Seth is in the bedroom with Anna and she goes to kiss him, I see Samaire like slip tongue,” Rachel said on the podcast. “I get transported back to 18 years ago and I get a little jealous.”

Rachel is talking about Samaire Armstrong, who played the role of Anna on the show. Rachel is referring to a big episode, “The Homecoming,” where Anna and Seth kiss.

“It was like the real-life triangle playing out as I’m watching it,” she said. Rachel and Adam dated on and off throughout their time on The O.C. before their final breakup during season four.

“I feel like it definitely played out a little bit in real life for a minute… even though not really really, but I remember the tension with Samaire and I like a little bit,” she added.
