Yeah, the moving in part did seem to come out of nowhere. Personally, I could see being a step-parent--it's the early years of childhood I don't care for, but once they're toilet-trained, I find them more appealing. I could imagine MJ in a stepmom role, as long as it was clear that Joe would never be her sole responsiblity, that if Jason was unavailable the child would be with Julie.

I think FWK is fortunate that Adam Scott is so appealing, because in the hands of other actors some of his lines would have been much more offputting. Even at his most body objectifying, I still liked Jason.
