She adores him.

From Ellie and Robert

This is the look Ellie gets in her eyes when she sees Robert. She adores him. She watches everything he does and is careful to notice all the little details about him, down to which teeny tiny animal is embroidered on his polo shirt. In the morning she inquires after him and stands by his door calling his name, hoping to find him awake and ready to play with her. She is very picky about the people she likes, but Robert passes the test. And she not only likes him, she adores him.
