I know it's a long shot, but it would be great if Telltale added something to understand the plot better.
I suppose that making the ending longer is not an viable option, but something in the extras could be a feasible solution... I don't know how exactly, an Elaine journal perhaps? ... or a pdf copy of the Keelhauler Gazzette? (Davey is dead, unfortunately).
I'm just dreaming, I guess, but think about it. An extra which filled the plot-holes would do the trick: everyone complaining about these problems (I know I'm not alone

) would be happy. On the other hand, everyone who liked the ending as it is, would still have the original unmodified game.

Everyone's happy.
