Back to the topic at hand, I'm sure that the Outsiders will appear in at least one of the Season 2 episodes. Scar at this point knows he won't get anywhere with these animals that are constantly failing their tasks. Most likely he's using them to gather information about the Guard and their weaknesses. Once his Outsider pride shows up (I assume he sent Ushari to get them), he will reveal his actual plan to them.

If my theory is correct that the Outsiders will have significance in the third season, Scar will tell Kovu that Simba stole his kingdom, slowly developing the cub into a younger version of himself and Zira; bent on defeating the royal family and taking over the Pridelands. Of course, Kiara (and maybe Kion) will try to tell him the truth, but Kovu won't be in the mood to believe it.
