A couple of thoughts on grammar:
1) Ship names ALWAYS need to be italicized.
2) Episode articles should be written in present tense i.e. "Billy informs Dufresne that he must fight. Dufresne is afraid because he has never even fired a gun." Character articles should be written in past tense i.e. "Billy informed Dufresne that he must fight. Dufresene was afraid because he had never even fired a gun."
3) References to characters should use their last name if possible i.e. "Bones showed Silver around" not "Bones showed John around". The exception to this, in my opinion, should be 'Eleanor' since there is another Guthrie.
