in her marriage, causing Sonya to "impulsively" slap Naomi. Morey admitted that she was uncomfortable about having to slap O'Reilly, as they are friends in real life. Sonya later apologised to Naomi, but told her to stay away from her family. Morey called it a "pretty satisfying" moment. Hate mail campaign and stalker In October 2014, it was announced that Sonya would become the focus of a hate mail campaign storyline. Toadie received the first anonymous letter which made "damaging insinuations" about Sonya and her past. He initially kept the letter from Sonya, deciding that he would investigate on his own.
