It was a shame with Jenny like othersn have echoed she seemed like a really nice girl. But she was going up against pretty big characters in a cult like following series (Pete, Glynn, Aisleyne, Nikki and yes even Richard to an extent) when she was a late comer.
I don't think she particularly did anything wrong in the series although I do remember her picking up some greif on here for being like the 4th person to tell Pete she had feelings for him.
