she didnt have an accident...she was still 'sick' when they went to the lake. She 'died' there and he was trying to wake her up but dunking her in the water....still weird but not as morbid as she 'had an accident at the lake'
I appreciate the clarification. Maybe I missed the part where there was an explanation that he was trying to wake her up? When I watched the film, it appeared that she had drowned or that he had actually drowned her... I had tried to find an online explanation of that scene... so, I guess this clears it up. Interesting movie, to say the least.
