When Teal'c is holding Klorel while Jack is trying to talk to Skaara, Klorel/Skaara's wig is obvious as it is shoved down his forehead further than usual.
When the Jaffa are all summoned to hear Apophis on the long-range communication device, the Jaffa woman in the second row, standing next to the sarcophagus, does not have a symbiote pouch. However, this woman does not have a Jaffa symbol on her forehead, like several other similarly dressed women in the shot, so it is possible that they are lesser Goa'uld. Also possible she is "Lo'taur", a human slave serving Goa'uld as described later in Summit (2001).
