Ender and his little Toadie

She's her own woman, spunky, opinionated, fearless (save big machines), but Ender is older, wiser and he knows it.  Its dawned on him to tap into the resources of his little sister to get things done.

"Cora, chase those pigeons!"
"Cora, pinch daddy"
"Cora, say you want to watch TV"
"Cora, say you're done with lunch and you want a treat"
"Cora, follow me"
"Get Gunther!"

At first, it seemed Ender was getting a little uncomfortable in the shadow of Cora and differentiating himself between that weird, loud urchin invading his once 'only child life".  But now, Cora has become more of an extension of Ender's will and dictatorship.  He is comfortable in his own skin and will use whatever means necessary to push some boundaries.  She is a weapon, mouth piece, and his little toadie. 

And they adore each other. until they don't.
