LAST EDITED ON 03-26-12 AT 01:29 AM (EST)Just for you I cued up the episode again and did some confessionals analysis.
During the tension headache sequence he had a tension headache confessional that was obviously not filmed during the tension headache itself. The tension headache was at night, the confessional was in the daylight.
He later had a dehydrated confessional post Tarzan's examination. This confessional and the tension headache confessional could have been one confessional split into two parts.
Tacking on as voice-over at the end of the dehydrated confessional were the severe pain die die die comments. Those could have been recorded post evacuation but were edited into the dehydrated confessional sequence as voice-over.
All of this were at the Manono camp, barring post-production VO. His final words, per the few seconds shown as they started, per beard growth, were not only filmed at a different time but at the Salani camp.
