Doctor Ash was a doctor who Sienna Blake called to examine Liberty Savage in November 2020, after witnessing Liberty talking with Sienna's deceased daughter Nico Blake (who Liberty was hallucinating). Liberty told Doctor Ash that Sienna was lying about her mental health to steal Faith Hudson from her. Doctor Ash ended up believing Liberty, and left. A couple of days later, Liberty hallucinated Doctor Ash and Sienna talking outside of Dee Valley University Hospital.
