Oban,like never before

Instead of Oban begining right after Eva joins,it happens a year and a half later. By then,'Molly has gained Don's trust in skills and asks her to join as a mechaninc,along with Stan and Koji. How different is the story of Oban,as we know it,going to be this time around? Rated T for strong language. Sorry for any mistakes I might have! Rick x Eva!
