Yeah, and I'm glad he was overheard like that, and that even Jane walked out. Ok, she sparked him thinking they would get squatters if no-one was there wanting to rent the place out to Billy and Honey, but he shouldn't be taking every decision, all the while expecting Jane to do most of the work running his businesses.
Phil doesn't want Billy when he's got plenty of family, and even then Billy's never done anything to Ian. It's a bit of a rubbish way to get back at Phil. Jane should rope in Pat - she convinced him to let a place out to Bert when he didn't want to, and Ian wouldn't like it if it was Bobby in Janet's position.
