Is Lewis after Audrey's love - or loot?

I'm loving Nigel Havers on Coronation Street as the charming and suave Lewis, are you?

But he's too charming, by half, I'm starting to feel, and I'm wondering if he'll start falling for Audrey but not in a way that she'd like him to do. I mean, I wonder if he's setting her up for freebie nights out, not charging her for his time, so that she thinks he really loves her when he's just after her cash? I may be wrong, of course but it's something that's already been hinted at a while back. What do you think's really going on with the fragrant Mrs. Roberts?
