What was the deal with the eels?
I get that he first discovered that they lived longer due to the water. But....
1. Why did Lockhart keep seeing/halucinating eels (in the iso tank, the toilet etc.)?
2. Why did eels appear when Hannah got her period in the pool?
3. Why did he make Lockhart swallow the eels? ANd how did he live after that??
1. Why did Lockhart keep seeing/halucinating eels (in the iso tank, the toilet etc.)?
A: Whatever was in the water that made the eels live a long time made people sick and likely caused hallucinations.
2. Why did eels appear when Hannah got her period in the pool?
A: The blood. The eat people, they were attracted to the blood.
3. Why did he make Lockhart swallow the eels? ANd how did he live after that??
A: Filtering the eels through a human body is how they made the "vitamins". Not sure how that works, your guess is as good as mine.
