in sg1 vala was a goa'uld
how did she lose here symbiont?
since she was a Egyptians goddess how come she's speak English?, Apophis speak Hebrew (or what ever the host speak) when the symbiont was dead
so about her father was what?, vala was a goa'uld for a long time, so it seem a bit weird that her father still alive and she seem not that ancient.
