These past two weeks I have been so impressed with Rachel's portrayal as Chelsea. She handled learning about the fling with grace, and she never let them see how bad she was hurting. I loved how she kept all her emotion contained and only had the pain reflected in her eyes. It was only when she was alone or with Theo that she let it out. Rachel is an amazing actress. I have not seen anyone else on the show who is more convincing at showing raw emotion.
The show needs to use her more and let her really have this complicated romance with Daniel. It has seemed to challenge Rachel and bring out new facets to her character. I have loved watching Chelsea grow and mature all these months.
