Lana does not die. Last we heard from her, she had to leave Clark because she was infected with kryptonite so she could not be near him. I don't remember exactly about a time when Lana tried to kill Clark.
If this is so, she was probably under the influence of something which cause her to act out of character. Clark and Lex slowly grew apart over the years basically because Clark is good and Lex is bad. I don't think it was one thing that caused their friendship to end, it was more like a series of things that happened over time.
Clark will not die in the Smallville series. Smallville takes place in his younger years and in the comics he does not die until much later.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
