I think it would be easier to tell her motives if she could make a few expressions. As it is with her blank face I can't tell if she's genuine or not. Although I can't imagine she's up to no good as Billy had to go find her and she's just discovered her daughter is dying. I haven't read anything on Facebook so don't know what's being said. However, as it's a soap something outlandish is probably afoot!
alot of people are saying about her face being without expression, some saying she wants Lexi after Lola dies, also she is lying about the burn on her stomach being from Lola's dad, some say she has been in prison, all guess work, we will find out soon for sure no doubt. I think last nights has put doubt about her in peoples minds when she hugged Lexi and said don't tell mum about the secret message in the locket.
I didn't see Friday's, I didn't think it was on. I'll have recorded it so I'll watch it later.
I suppose if she takes Lexi that'll be one way of getting rid of Lexi after Lola goes. Then Ben/Callum and Jay can have new story lines but keep in touch with Lexi off screen until she returns in her teens/twenties as Lola did.
