Since, within the GLOAQ thread it was specified that Grapple cannot actually grapple more than 1 figure in a given square, thus allowing another figure to "pass" through the figure grappled, and not be grappled by themselves.
Given this, assume a hero steps into a water square and his turn immediately ends. Can another hero step through that hero, and subsequently step through the water space without his turn immediately ending? Kind of like using his hero for a stepping stone? This seems to be consistent with the grapple rule above.
How would you rule?
