Shallan was Ba'al's most trusted lo'taur. Kanan, a Tok'ra operative working in Ba'al's compound, used her to obtain information. What he didn't expect was that he would fall in love with her. After blending with Colonel Jack O'Neill, Kanan attempted to free her but was cornered and fled his host; O'Neill was captured by Ba'al and tortured. O'Neill and Shallan were able to escape after SG-1 informed Yu of Asdad, and Yu attacked it.
