Lola

So Lucas tells me he has a girlfriend named Lola. He talks about Lola all the time. She's always playing with him in the playroom, watching a movie with him, or in the car with us. Problem is, I have no clue who Lola is. I don't know if she's a girl at school (I know there isn't a Lola in his class), at church, or at the Y. Or if she's from a movie or a TV show he watches or if she's completely imaginary. If that's the case, I wonder how he came up with the name Lola. The name is pretty cute, I must say, especially when he says it.
