Booth and Brennan are actually discussing having children at the end of this episode. Not necessarily together, but it still sounds pretty awesome. Booth then starts talking about what Brennan can do with her money - and he shows his childish side.
There's also a very touching episode where Booth makes Brennan stay in the car with a promise that she'll think about the baby - not him. It's obvious they know the other has deep feelings for the other, and Booth convinces her to set her feelings for him aside to protect the baby.
After a woman is killed in a suspicious car accident, Booth and Bones wonder how the woman's baby survived it. It was practically a miracle, even though Bones would never use the word miracle. Since the woman hasn't been identified, there is no one to take care of the little baby. So Booth volunteers to babysit. Bones going along with it, eventually learns to really like the baby. Maybe she would be open to having a baby one day (wink, wink). Get it? Because Bones and Booth have a baby in Season 7. Spoiler alert!
Overall, I give this episode a 7 out of 10.
