played by Pauline Collins
Gaius's heart is sent racing by his old flame, Alice. In the days before the Great Purge she was a great healer whose magical abilities were renowned across the land. She was forced to flee or lose her life and she gave up the one thing that she cared about above all else: Gaius. The two are reunited when she returns to Camelot, but the old physician is not her only reason for returning.
