<p>I was the one who added the "as of the series finale" part. I didn't take my time to see if their ages were correct.
</p><p>Actually, the timeline is pretty clear. I just realized that, but it is clear: they all, in 2016, are 18. Four years later (2020 in the episode), they appear on The Helen Show, and 10 years after The Helen show reunion (2030 in the episode), they all are shown with their partners. This means that their real age as of the series finale is 32.
</p><p>I think some users got confused with this timeline thingy, but when you stop and analyze it for a while, you realize it wasn't that confusing after all haha.
