 He called Wilson "Uncle Arthur" and, although never explicitly stated, it was often evident that Wilson and Pike's mother were in a relationship, which they unsuccessfully tried to hide, and Walmington is rife with gossip about the couple.Wilson is often seen having meals at Mrs Pike's house with Frank, and Pike mentions several times that Wilson spends the night (although he believes he sleeps on the sofa, whilst Wilson accidentally lets slip that he was in fact in bed with Mrs Pike).It was also occasionally suggested that Wilson was Pike's father (although the writers only acknowledged this in interviews after the programme ended).
