Romana is in the TARDIS wardrobe room. She has just met the TARDIS wardrobe mistress, Iraj, who she learns is a shape shifter. Iraj wants to play a joke on the Doctor. Romana has no patience for this right now. She can feel that a regeneration is near. Although most Time Lord regenerations occur when the Time Lord body is damaged beyond repair, sometimes subtle damages build up. Romana thinks this is what happened to her, with the chronodyne's influence starting the process. When Romana finally regenerates, she is shocked to discover herself in Astra's form.
