Aimless Ramblings of an Athenian

Admin Rant, so you can skip if you like

Hello, it's the admin here.

Anyway, I have something that's been bothering me since I first got into the Percy Jackson fandom.

And that is the fact that most/all of Athena kids have blonde hair and grey eyes.

THIS HAS ALWAYS ANNOYED ME.

Annabeth has blonde hair and grey eyes, correct?

She has blonde hair because her dad does, I'm assuming. And grey eyes because of Athena and crap.

That makes sense, right?

But then it mentions that almost every other Athena kid has grey eyes and blonde hair. There's where I have a problem.

How can all of her kids have grey eyes? She could influence the child's appearance, I suppose, because of the fact that they come from her head or whatever, but why would Athena do that? She doesn't care about looks at all, and eye color is hardly very important. Only what goes on in the head. More on this later.

And then there's the thing about them all being blonde. Athena appears as dark haired every time we see her, so it's reasonable to assume that she also appears as dark haired when she meets/ falls in love with mortals.

(I'm assuming that however the goddess/god appears as is what the kid will look like. Take Percy for example. Poseidon usually appears as a dark haired dude with sea-green eyes, right? He appeared that way to Sally, too. And Percy looks EXACTLY like Poseidon. So that's my logic.)

So it's reasonable to assume that a least a few of Athena's kids are going to inherit some dark hair, right?

And that's just assuming that whatever mortal she falls for isn't dark haired. Most of the population is dark haired, and the chances of Athena only falling in love with only blonde people is extremely unlikely. 

If Athena were to alter her offspring's appearance and the mortal parent didn't resemble the child in the slightest, how would the mortal parent explain this to other people? There's always the adoption card, but how likely is this in cases where parents weren't ready for children, like in Mr. Chase's case? And then there's things like "oh they just look like their mother..." or whatever, but how believable is that when there is absolutely no trace of said mother? 

That's just some of my reasoning, and there's obviously some more reasoning, but I'm too lazy go into it right now.

Anyways, what's your opinion on this?
