Where go?

Does Sophia know Chinese or English better? I can't tell.
Last night, when we were having dinner, Sophia dropped her spoon. She looked down and said, "where go?" I knew she was trying to make us believe she didn't do it on purperse.
After dinner we decided to go shopping. After being put into the car, Sophia said, "where go?"
It looks like she knows the meaning of those words really well.
