This is Isabel Oliver Marcus, a San Antonio native and North East School of the Arts alum. She's going to make watching "This Is Us" even more fun because, starting Tuesday, she'll be portraying the girlfriend of the teenage Randall!
You may have noticed her already in the season premiere. She wasn’t identified and had no dialogue. She was just seen sitting on the couch with Randall and comforting the tearful teen and his sister Kate after they learn their father Jack has died.
She'll be in four more episodes but, you never know, there could be more! “It’s such a huge, huge opportunity,” she said.
