Sheyan could only shrug off the Protoss leader's attitude. He knew the world did not revolve around him, and no one had any obligation to show him goodwill. He had never been that kind of lucky character. In any case, he had already achieved his objective, which was to obtain the right to freely enter and leave the Protoss base.
For Sheyan, looking for a Dark Temple that had been deliberately concealed on this vast Lost Temple planet was no different from looking for a needle in a haystack. Instead of going around aimlessly trying his luck, he thought that moving together with the Protoss forces and waiting for an opportunity to present itself was the better and safer plan. He could attack or retreat at will by hiding in the Protoss base.
