Charlotte Hoyle Charlotte Hoyle was a teacher and former colleague of John Stape . Charlotte was the Head of Religious Education at Fairgreen Comprehensive School . When Colin Fishwick threw a party to celebrate leaving the profession in April 2010 , John attended despite no longer being a teacher , and enjoyed reminiscing with Charlotte about a school trip to Nottingham . Colin ' s move to Canada gave John the idea of stealing his identity to get back into the teaching profession . Two months later he attended an examination marking conference and was horrified to find Charlotte was also there . John had previously checked the attendance list to ensure that none of his old colleagues were present but he only checked by school name , not knowing that Charlotte had left Weatherfield High . He initially pretended to be working for the examination board but when Charlotte noticed Colin ' s name on the same attendance list and was stopped by John from " correcting " the matter with the organisers , he was forced to confess the deception . The somewhat vampish Charlotte confessed that she now found John exciting whereas she previously thought he was boring and insisted that he take her for a drink . John was startled when Charlotte turned up on the Street with the claim that Colin was returning home but when he questioned her further , it turned out that she ' d only received text messages stating that he wasn ' t totally happy in Canada . However , Charlotte made great play of knowing John ' s secret , both to him and Fiz when she found the pair together in the Rovers , having been told by Rosie Webster that the old teacher had a reputation for being a " slapper " . Fiz demanded that John gave up his deception and resign from the school . Charlotte later began sending John letters , claiming to be from someone who knew about them hiding Colin ' s body beneath Underworld . When John confronted her , she claimed she had nothing to do with it and gave him a letter , apparently sent to her ( although she created it to fool him ) . However , John later discovered cut - up newspaper in a drawer which she used to create the letters and confronted her . Charlotte then told John to live a double life with her under the name of Colin , which he accepted as he didn ' t want any of the truth revealed to Fiz . When he joined her for dinner , she invited her parents round claiming that she and John were engaged and that they would spend Christmas dinner together . When John told her that it wasn ' t working out , Charlotte agreed and told him he should leave Fiz and move in with her . John " agreed " to it and went home , but didn ' t tell Fiz . On 6th December , while Fiz was at Leanne Battersby ' s hen party at the Rovers , Charlotte turned up at the house . When John told her that he couldn ' t leave Fiz , Charlotte became hysterical and attempted to attack him with a hammer . He wrestled the hammer from her and she told him that she was going to reveal the truth to Fiz . As she reached the front door , John hit her in the back of the head with the hammer and she fell to the ground where she lay motionless and bleeding . After taking a moment , John decided to dial 999 but was interrupted by an explosion at The Joinery bar on Viaduct Street , which in turn caused a tram crossing the viaduct to derail . John left to search for Fiz and upon learning that she was injured and in premature labour , he had to leave Charlotte at the house and accompany his wife in the ambulance to Weatherfield General . He later returned to bury Charlotte ' s body in the rubble to make it look like she was caught in the accident , but a policewoman who discovered her revealed that she was in fact still alive and called for an ambulance . At the hospital , John was about to switch off Charlotte ' s life support machine when he was interrupted by her parents . John and her parents were later informed that there was litle likelihood that Charlotte would survive and if she did she would suffer serious brain damage . Charlotte ' s parents asked John , who they believed to be Colin Fishwick , what he would want to do , to which he responded " Let her go " . Charlotte ' s life support was then turned off and she quietly passed away . List of appearances . 2010
