If you're looking at chp 1 page 5, 12, 18 and 34, the one she save is not the emperor right? It seemed to me like she saved Sidis instead because from her memories, the emperor have the same hair as he grew up and next to him is the one she saved and have different hair from the emperor. So obviously that's Sidis, no? Maybe i'm wrong but i strongly got the impression that she saved Sidis.
