A Question for Christians

[Lestat]

Through a medical marvel brain transplants have become possible. During the process the brain retains 100% of it's capacity and loses no memory or intelligence whatsoever. So with the exception of having to re-condition itself to its new body, the brain funtions exactly as it did before the transplant.

Suppose we take George's brain and put it in Harry's body; and Harry's brain and put it in George's body.

Questions:

1. Which one is now Harry and which one is George?

2. In which body does George's soul reside?

3. If the body that had Harry's brain before the transplant now commits a mortal sin, who's going to hell? Harry or George? (please specify which one is which).
