Emily was first played by Amber Tamblyn. Amber was a great actress and did the character justice. I personally liked the way she was introduced. There is a number of ways that Emily could have been brought to the canvas, but the Cancer storyline was poignant and gave Monica female support.
Amber left for greener pastures and they brought on Natalia. I guess Amber was the teenage Emily and Natalia was the adult. I really liked her performance and she really had chemistry with most of the cast.
Note: She also returned as Emily's twin sister in 2009. Since we didn't know Emily's true origins as she was adopted, this wasn't a bad narrative. It was found she was only after Em's money and ended up leaving for Paris --on a plane, with "Zander".
Oh, lordy, Natalia's Emily. I loved Amber. She's grade A++ in the acting department. Nat was good but not spectacular. Emily was softer and older. Then they paired her with Sonny and my brain fell out. What a terrible, terrible pairing. I knew it would NEVER have happened with Amber in the role so it was double weird. Why they killed her off is still a huge mystery to me. It was the "blow up the Quartermaine" days at GH. The twin sister idea had traction since Emily was born to another mom before the Qs. That didn't last long though!
