Leonard Caul (No. 62) - S2-E19
Other mistake: When Reddington is close to death and is saved by a lung/heart operation in his field hospital, minutes after the operation the site is attacked and Red is left trying to defend himself from gunmen. Not only does he find the strength to pull out all the monitor wires and lines attached to him, but when he goes into the corridor to get a gun, he is fully dressed in jacket and trousers (pants). Did the very efficient hospital team forget to bring a hospital gown for him to wear? Did they operate on him while he was wearing his street clothes?
