I am sorry, but as cute as Iki is his idea was reckless and it would have endangered everyone. I understand why Iki wants to go back, but it is not safe and if he gets killed the world will be in serious trouble. Raigho wants to keep his pack safe and he has the right idea to keep going. Not to mention that Raigho is dealing with stress from everywhere.
He has only limited time to take Iki to the destination and Hati wants him and the pack to travel on a faster, but more dangerous route that could kill some of the pack. There is also the fact that Fehu is starting to want answers and a fight almost happened, Gebo came back with a injury that left tracks for Seven to follow, and Iki stepped out of his boundaries. Raigho has to remind everyone that he is the alpha male and Iki has to learn that it is not good to step out of bounds like that.
