Did Cesar die at the end?
Couldn't tell if he survived or not. Too many "foghorn" use at the end.
No. He was shown to be safely in a lifeboat. (One of the Ship's Officers put him there because he'd had a knock on the head) It was announced at the end that the ship was stable, and that help was on its way. Also that the lifeboats were standing by, so that passengers could be reunited with their loved ones.
"I do hope he won't upset Henry.."
