In hindsight, the thing that bothered me the most about the Amy/Gina plot last episode was that Amy wasn't allowed to even temporarily pull one over on Gina (by slashing her tire).

I think Melissa gave birth to her baby very soon after they completed filming Season 3. They finished filming Season 4 around two months ago and I'm pretty sure that Chelsea is still pregnant now.

I don't know how Gina was forced. Gina negotiated a free lunch for herself, at Amy's expense, in order for Amy to do her tutoring session.

Yes, this makes me enjoy the character a lot less. It gets annoying that Gina can basically act as horribly as she wants and she'll most likely end up being proven right at the end of a storyline. If any of the other character acted the way that she does, they would learn something at the end. Gina though, I feel…

I still like the character, but I do agree that the writers can really go over the line with Boyle's obsession with Jake and Jake/Amy. I think when Boyle fanboys over Jake/Amy being "America's dream couple" its funny and fine. Everytime Boyle talks about Amy becoming pregnant with Jake's child though, its super creepy.

Unless they retconned it, Jake said he was 33 in Season 1, so he's probably 36-37 right now. Chelsea Peretti is a few months older than Andy Samberg in real life. I could see the characters being 2-3 years younger than the actors that play them. Jake and Gina being 36-37 and Rosa being 34-35.
