I think she used to constantly persuade Paige to do things with her, going out for meals etc and I believe Becki managed to get her to come with her by always paying for the food and trips out and now Paige has grown up and has her own life she’s left to her own devices which is why it’s always her sister Rachel that’s going with her now. I think Becki bribes her too. Paying for meals out, gigs, nights away with hot tubs. I reckon she loves to splash the cash to get what she wants out of people (company while she stuffs her face in restaurants so she doesn’t have to go alone)
