Will Griffiths was a drugs counsellor at Weatherfield General who saw Leanne Battersby for several sessions in January 2000 to help her overcome her recently acquired drug addiction. Their sessions got off to a rocky start when Leanne was antagonistic to him and she almost walked out when she saw a packet of cigarettes in his briefcase, accusing him of hypocrisy. He persuaded her to continue although in truth her own determination and the pleas of her family had more of a positive effect on her eventual rehabilitation.
- Will was played by Tristan Gemmill, fifteen years before appearing in the regular role of Robert Preston.
