From this, the only thing confirmed about the two hour episode is that it'll see Ruby, Merida and Mulan on an adventure: http://www.ew.com/article/2015/10/09/once-upon-a-time-panel-new-york-comic-con-2015

We also know the date. Until anything else is revealed, we should stop panicking aboutt he episdoe count etc.
