Juvenile Gray Catbird?

Not sure about this bird. It looks like a type of mockingbird or flycatcher to me, but not sure. I have three different shots of it. Maybe someone can help ID it. Northeastern South Carolina, USA. For now, I'm going to call it a Gray Catbird, since a few people think it might be that.
