She has a different look in Music Lesson. Something about the eyes especially in the scene when they are headed to the band recital.

Her hair was done differently. It looked like it was pulled back from the front, and it did make her look different from the other early episodes. I didn't notice that particular scene.

Her makeup looked different too. Didn’t see New Doctor but think she was back to normal. Don’t know if that was the next episode filmed.
