Seriously, did anybody NOT see that coming? You'll notice I didn't even bother with a spoiler warning.
Here's a hint. If the big reveal is going to revolve around somebody's baby not being their biological kid, stop doing that "light-haired parents, dark-haired kid" thing. Everybody does that when doing adoption or switched at birth or whatever, and it's cool, except that it ruins the twist ending. So if we're not intended to figure out the plot of the episode 10 minutes in, sacrifice convention and have everybody running around with the same color hair for a change!
Also? Everybody and their dog knows that two blond parents don't have brunet kids. Of course, everybody knows a lot of things that don't turn out to be true, granted*, but all the same - with that bit of knowledge firmly implanted in the cultural consciousness, how can these people be so! shocked! to find out that their kid isn't genetically their kid?
Why isn't this up on TVTropes on their entry on "Switched at birth"?
*I don't even know if it's true or not anymore. Sorry.

It's like drawing a picture with only a charcoal pencil - you can still do shading, but you're doing it with that one tool.
2. There's a gene to reduce how much pigment you have. There's several of them. Your cousin has one type of pigment reducing gene - let's call it light. Her husband has another. LIGHT. Since they don't match, they do largely bupkis together, so their kid ended up with dark eyes. (I imagine this goes doubly so if the genes that reduce pigment are in different locations, in which case he could get a "have dark eyes, like normal folks" gene from each parent without any problems.)
3. You never heard about this in high school bio class because a. your teacher wasn't a geneticist b. they didn't know this yet and/or c. high school bio classes are stuck on basic Mendellian inheritance and have no interest in going beyond that.
I'm sure
