Grace Piper Grace Piper was a friend of Faye Windass for a few months in the autumn of 2013 , both in and out of school , and whose bullying manner and psychopathic tendencies caused problems . Grace was one of the most popular girls at Weatherfield High and drew others to her flame , wanting to be part of he " in - crowd " . As a result , she had little or no empathy with anyone around her though she hid this well beneath a veneer of politeness . When Anna Windass and Owen Armstrong , Faye ' s parents , first met Grace , they were taken aback by her self - assured manner when she complemented them on their home . They were further impressed when Grace pushed Faye into doing their homework immediately and not putting it off until later . They questioned her over dinner and found out she was an only - daughter whose father was a carpet fitter for hotels and other large establishments while her mother ran a card shop . Behind their backs however she freely admitted to Faye that she played people well to get more out of them , such as her expensive shoes that she had wrangled out of her parents . After a couple of weeks , Faye grew upset when Grace appeared to have dropped her from her intimate circle of friends but her fears proved unfounded when he made contact with her again . One effect of Grace ' s influence was that Faye started to become more cheeky and outspoken , especially with Sally Webster once she started a relationship with her father , Tim Metcalfe , resenting them being together . Grace engineered an argument between Sally and Anna over some change in Roy ' s Rolls which caused Faye some qualms but Grace egged her on to push Anna to host a fancy dress party on Halloween for her to enable her " overcome " her upset . Anna agreed , though Owen could see through Grace and saw the negative influence she was starting to have on Faye . At the party , Grace , dressed in an expensive hired costume , was malevolent towards Simon Barlow , picking ruthlessly on the young lad both for his cheap mummy costume and about his dead mother . She also made fun of Nick Tilsley who was recovering after sustaining head injuries in a recent car crash , not impressing Owen nor Sally who overheard her comments , the latter making her views quite clear on the subject . Grace ' s next prank was to try and cause an argument between Tim and Sally . She and Faye invited themselves into No . 4 and when Sally went to the shops , they rang Tim and pretended there was someone trying to break in . Putting on a show of being terrified , they brought him rushing back and he argued with Sally , just as they had planned . Grace ' s next target for her attentions was Mary Taylor who earned her resentment when she gave her and Faye unwanted healthy eating advice as they were tucking into a burger in Roy ' s Rolls . Pushing Simon into joining them , they threw stones at Mary ' s motor home , and then wrote on the back in shaving foam . They were caught red - handed by Mary , Norris Cole and Emily Bishop , the latter being threatened with being sued by Grace if she touched her . The group of kids ran but Owen was on the scene and heard the allegations , later apologising to a tearful Mary though Anna reluctantly accepted Faye ' s innocence . Grace then pushed Simon into stealing sweets from the Corner Shop by taunting him that he was only a little kid . He was almost caught by Dev Alahan and went back to the girls at No . 6 where Leanne Tilsley ran him to ground . She and Owen had their suspicions that the girls had put the lad up to the robbery but Faye , when questioned , stood up to Owen and answered him back in a style previously prompted by Grace . Grace ' s attention then turned back to Mary and she repeated the stone - throwing when she and Faye were supposed to be at dance practice . Mary complained in strong terms to Anna who that night asked the girls how their practice had gone and received a convincing answer , even when asked directly if they had been behind the vandalism . Izzy Armstrong was present on this occasion and , like Owen , started to wonder if Grace was too good to be true . Anna also had some doubts but had no firm evidence on which to base her suspicions . Things reached a head when Tracy Barlow paid Grace and Faye to walk Eccles , taking both Simon and Amy Barlow with them . They gained access to No . 1 with no adult supervision where the two elder girls wreaked havoc , scattering clothes all over the place and smashing a vase . When Simon tried to leave , Grace got Faye to hold him down while they forced him into one of Amy ' s dresses and covered his face with make - up , all the time recording the incident on Grace ' s mobile phone . Leanne was appalled when a tearful Simon burst into the bistro but before she could get to Anna , Tracy got there first complaining about the house damage . Anna was floored by Leanne ' s accusations but recovered her equilibrium when her daughter was accused of being a " vicious cow " . Anna demanded the truth from Faye , who said that Simon was a liar and stood up for her conniving friend . Owen was convinced of Faye ' s guilt though , and banned Grace from their house . Simon refused to go to school where the footage that Grace had recorded was passed round on everyone ' s mobiles after a fight between the two girls when Faye tried to get the original deleted . Faye was suspended and Anna was at her wit ' s end . Worse was to come though when Asha Alahan received a copy of the footage and showed it to Mary who in turn passed it to Tina McIntyre and then on to a livid Peter Barlow . The scales were pulled from Anna ' s eyes as she watched the recorded events but worse was to come as the footage had made its way to pupils at Bessie Street School , leading to phone confiscations and complaints to parents . Having viewed the footage , head Brian Packham had to follow policy and report the assault to the police . Anna and Faye were summoned to Weatherfield Police Station , as were Grace and Mrs Piper , who robustly defended her daughter . Faye found out that Grace had put the blame solely on her and , as a result , came totally clean herself about events and her own fear of Grace . With the threat of prosecution hanging over Faye , Anna threw herself at Leanne and Peter ' s mercy and any charges against her daughter were dropped . To everyone ' s relief , Grace ceased to be a part of Faye ' s life . List of appearances . 2013
