Answer:
Lehna connects with her audience through thoughts common to most people. This generates identification, which allows a credibility with the character to be established.
Explanation:
As you can see in the question above, Lehna expresses feelings that make him feel inadequate and rejected by society. He feels that society judges him and does not accept him for things of the past. He feels lonely and disengaged from this world. These are feelings common to every human being. We all feel that way as if the weight of all the judgment in the world is on our shoulders, just as Lehna feels.
This makes the audience create an identification with the person and as everyone knows these feelings, the character gains credibility and his drama makes sense to the audience that accompanies him.
D. Iambic pentameter
Eventhough Robert Frost did write in several meters his favourite one and the most used was iambic, he was very good changing little parts to hide iambic meters, so he´d write in iambic but still sound fresh and his poems seem to flow better.
I was gonna answer it but the other person beat me to it.The answer is correct.
Oh boy.
If this is story is planned to end with crazy plot twist i suggest you try to figure that out.
I'm thinking that the girl maybe early adult is living in an apartment with her (insert mental illness) twin and is put into several life threatening scenarios such as car crashes, drugged drinks etc. She doesn't know what is going on but she eventually, though means of spying or accidental, she learns that it's her twin. Maybe some twilight zone hitchhiker he keeps appearing anywhere sort of ordeal. I don't really know what genre you're going for but I think a very realistic interpretation and non-paranormal would be pretty awesome.
I don't have many ideas right now on murder motives besides some sort of schizophrenia or brainwash/temptation. But the story sounds great.
Best of luck!
