Tracy Barlow's Return in Corrie?

She`s let out for Blanche`s memorial service. She has had a taste of freedom so when they propose that she try to get Gail to confess to her about murdering Joe so that she can get an early release she obliges only she twists Gail`s words to make her sound guilty. I`ve read that many people are glad that she`ll be back but I`m not one of them especially this way.
