I'm impressed with her as well. I also liked her reaction to the FIR. The girls who are either sobbing or gushing or swooning the first night seem ridiculous to me. Sharleen had what, a total of probably 10-15 minutes alone with the guy, and he was impressed enough to give her the rose over 26 others...I think she was pleased, just a bit reserved and restrained in her reaction.
A little restraint is a good thing on this show!
