This episode. It had no sparkle - Corday storyline was most catching as she was in most awful situation and maybe she found the real person to blame.
Also the new med student, Gallant arrives and he misdiagnose a patient and another second year med student, who is patient, has the right answer. Gallant looks promising and the patient-med student - her story and the way she looked first so harmless and what we learned later - it was well written.
But all the thing between Susan and Carter - I do not know where it came from. But Carter's grandmom - I think there is coming something promising.
