For Isabel, hi, cutey. Regarding the scene at Dumai’s Wells, the places they had Traveled to were not in the safety of the wagon-circle, where they were, but beyond it, among the Shaido. As for Illian, I was too crude in reinforcing something I had established earlier and wanted to reinforce, i.e. that you do not need to know a spot at all to Travel from it if the place you want to travel to is only a short distance away.
Regarding Sharina, and other women who learn to channel at age, she will indeed grow younger in appearance. No, she will not achieve an Aes Sedai face without the Oath Rod, but where she has previously looked, say, sixty, she will look perhaps thirty-five, with accompanying changes in hair color. Think of it as analogous to slowing, which older women also do.
