I agree she is a tart with a heart and as I have said earlier I do feel sorry for Leanne but not entirely as I feel she has brought her misery upon herself by not being honest with Liam and weaving a web of lies not only with Liam but with the other Connors (except Paul of course) which contributed to pushing Paul over the edge.
Leanne like Paul had/has emotional issues, hers being the famous Baldwin love triangle which messed her up and is the reason she turned "Escort" for protection and money and has led to her downfall. The reason why I am looking forward to her comeuppance is because up until the other night she was golden girl and Paul was bad boy now the tables have turned on her..
