Jala is very short and has grey hair, a sign of very old age among Aes Sedai. She is an imposing woman.
One of the Aes Sedai involved in the capture of Egwene was named Jala, and as she was of either the White or Green Ajah, it can be assumed this was Jala Bandevin (KoD, Prologue) and that she sided with Elaida after the split.
