I for one am suprised at all the support today; I love it, but it's eerie. I keep waiting for "HE HAS A KID?!?? KEeP THAT CrAZY BITCH AWAY!!!!"
As for the daughter (I'm hoping for the name Lucy) addition:
I don't really think he's going to introduce the two of them quite yet, and the possibility of staying over is now sorta eliminated.
I like this added factor, Jim immediately becomes more responsible which is both attractive and necessary to Dora right now. He's got things to take care of all of the time, which could be really great for her. Yes, she might and probably will get irrationally jealous at some point, but unlike Marten, Jim won't have time for her to act out.
Probably though, the flames of their love, like Jim's kitchen, will become extinguished.
