We've only got a few hours before the island sinks, yeah?  So in order to keep our timeline smooth, we need to send back a horse now, right?  Before we reach Romenna, as the trip, even on the Energizer Kariborimbunnies, takes at least a few hours.  Also, whoever writes that in should account for what this horse has been doing while riderless.  Surely the Faithful would notice a passengerless horse cantering along-side them?  
On the plus side, my characters currently don't have the mindset to notice Abarzadan gone.  Kath's dying (maybe?  haven't decided yet.) and Inzi's blaming herself for it.  I feel that I really must foist this twist off on someone else, as they just can't deal with it.
