Playing as a male exile I just completed Telos and entered the Ebon Hawk. Watched the cutscenes of both the trial and the list of masters and handmaiden failed to make herself known. I've looked online for any potential explaination and was able to find the following in a list of changes:

Handmaiden will no longer always be send with male PC's. Depending on your choices in Atris dialogue she will now be send or crawl on your plane, with slight variations in a few cutscenes as result

While it explains what may be the cause I have had no luck in finding what it is I specifically need to say to Atris. If anyone knows anything at all I would greatly appreciate the help.
