Lucy Sobel
From Tardis Wiki, the free Doctor Who reference
Lucy was a co-worker of Rhys Williams at Harwood's Haulage.
She originally moved to Cardiff from Bristol. She first met Gwen at a barbecue in Ely where Rhys and a group of other guys were busking some Kaiser Chiefs music on a bass guitar. Gwen remembered that Lucy had been at least a size 16 at the time.
Gwen Cooper was convinced Lucy had feelings for Rhys. After this, Lucy unexpectedly got caught up in one of Torchwood's investigations. (PROSE: Slow Decay)
