Presumably this is a love interest for Nico: http://www.digitalspy.co.uk/soaps/s1...e-regular.html

I wonder whether that means there will be a twist about Sienna or Dodger's paternity?

I'm still not convinced it's Dodger. Patrick knows full well that him knowing would break Dodger and Maxine into bits. She'll tell Dodger all about it and he'll be like "I wasn't there, that wasn't me"

I cant believe the police and social service havent looked in to nico living with a stranger

If she has any sense, she'll run like the wind, while she still can.

He's not really interested in breaking them up; he just has a control fetish. He wants to feel as if Maxine is enslaved to him but I don't think he really wants her back.

I'm surprised he hasn't dropped some hints to Maxine though or made some snidey comment. No doubt something will slip out in the future.

I suppose also that Patrick is using the Dodger secret to control Sienna. If that got out, he'd have nothing to control her with. And on a less cynical note, he does care about his daughter and would want to protect her, I imagine.
