I've been rewatching DA season two and three and watching Mrs. Patmore and Daisy again and again the less I like Mrs. Patmore. Daisy only likes William as a friend but Mrs. Patmore is more interested in William's feelings than Daisy's so she forces Daisy to let William think that they are sweethearts and then allows William to tell others that they are engaged. Then when William is dying she forces Daisy to marry William over her objections. Then she manipulates Daisy to accept William's father. Then in season three when Daisy becomes besotted with Alfred and tries to tell him how she feels Mrs. Patmore is always interrupting Daisy and Alfred. No wonder Daisy became nasty towards Ivy and no wonder she was nasty in later seasons.
