Even if Merlin didn't want to bother Kilagarrah, he could have called him sooner. It really made no sense that he waited that long, other than Arthur had to die per the legend. Heck, he could have even called Aithusa and given him a little redemption, and turn him from Morgana's evil, vindictive ways. The ending was sad and disappointing because several things were dictated by the plot, not logic.
