The Goa'uld had no idea what was coming, and so they were taken completely awares as the strange figure appeared in their midst. The decloaking and noise caused the Jaffa to whirl about, staff weapons pointed at the figure for brief moments before bright light caused a diversion to keep from being blinded. The fact that this being could speak their language was not as much a surprise as Nim might think, but there was undoubtedly some alarm, only balanced by the certainty that they were in the presence of a mighty figure that demanded answers from them. 

But Teal'c had not been chosen as First Prime simply because Ba'al had seen his capabilities in another universe. No, he had certain qualities that Ba'al found advantageous, and that was his loyalty in the face of such an awing presence, a determination that allowed him to act as he reoriented his staff weapon upon the figure. "You are mistaken," he replied with a firm tone and weapon at the ready. "This land belongs to the God Ba'al. Identify yourself and explain why you have attacked the Jaffa living her, or there will be consequences."

Perhaps he couldn't actually harm this figure, but it would not stop him from doing his duty.
