Jim and Pam have their baby on tonight's episode of The Office, marking yet another step toward adulthood this season for the fresh-faced couple—along with Jim and Pam get married and Jim gets promoted to co-regional manager of Dunder Mifflin. Big changes for a couple that first bonded over how much they hated the Dunder-Mifflin management back when Pam was engaged to someone else.

In an interview with Vulture, Jenna Fischer, the actress who plays receptionist-turned-paper saleswoman Pam, explains her character's life changes as inevitable:

In the first few seasons, Pam and Jim loved mocking the system. Now they are the system.
A little bit. I think what is sort of cool about Jim and Pam is that we watched them grow up—and thankfully so. Because I think when you get into your 30s and you're married and you have a family, it's realistic to become a part of things. You can't just mock the system for your whole life—that's youth. I think it would have gotten boring and repetitive if they had stayed at that one level forever. I'm really happy we get to grow.

But maybe the show's writers are spending too much time letting Jim and Pam grow. Ta-Nehisi wrote earlier in the week that he's "leaving the office"—mainly because the show has become too focused on the couple. Here's hoping that after the baby's born we see a little more growth from the other members of The Office—before NBC changes the name to The Jim and Pam Show.
