Half-O turned two ...allegedly

As mentioned in the previous post, Half-O turned two (back in the beginning of November).

She had a good day: read in the backyard tent with The Archaeologist, channeled Cinderella til lunch, got to ride in a tow truck, ate dinner one-handed so she wouldn't have to let go of her new calculator, rode the merry-go-round, and blew out her two candles all by herself.

{Yes, her two gifts were an elaborate Cinderella gown (+ crown) and a calculator. No, not because we are ham-fisted parents forcing some sort of toy balance, but because that's what she wanted. She has very decided ideas regarding her gifts. Today she walked up to the Santa at the grocery store and repeatedly told him that she wanted a pink book and a Kermit for Christmas - just repeated it over and over as he stared down at her. Then he finally gave her a candy cane, looked at me and asked, "de que pais son?"}

Throughout these two years of her life, I have been increasingly suspicious that Half-O is not just the infant/toddler she ostensibly ought to be. On more than one occasion, she seems to have forgotten the ruse and almost blown her cover, like last month:
We were singing that song from The Sword and the Stone - the to and fro one - while playing with her animal dominoes. There's the line with "thin and stout" and I stopped and asked her if she knew what stout meant, entirely intending to define it for her in the next breath - but, she absently answered "fat". Now this isn't a song we sing often - she doesn't really know it. I don't remember previously defining stout for her, and if I had, I don't know that I would've said fat - but even if at some point I did, it would have been quite a while ago. She may have deduced that the song was explaining the existence of opposition in all things - but is that less fishy? So I incredulously asked how she knew that and she suddenly became very interested in her dominoes, and then when I asked again, "so, what does stout mean?," she did some non-committal mumbling.

Or the other day:
We were doing some coloring and I asked what color the horse should be and she said, "gray - like a winter day."

Then there are these cleverly couched comments, like back in the spring:
We were standing in line at the store, and I was holding her on my hip when she proceeded to knock on my head and ask "anybody home?".

Or last week:
She said something was very funny, but I didn't catch what that something was so asked, "What's very funny?" and she responded "Look in a mirror."

Seriously she said that.

She doesn't have older siblings, she doesn't play with kids who speak English, and we don't have a TV. So how is she throwing out insults at a 3rd-grade level?

changeling? G-Man? a result of all that protein I ate in the last trimester?

Looking forward to year 3.
