Yes it is in english, as for the specific missions during the Van Wynter Legacy when confrontung the cult leader the sister of battle says "The man, the myth, the Legend" when the cult leader is a woman.  The next encounter it happened was during the same chapter when confronted by the other inquisitors on uthers sanctuary the other inquisitors orders his troops to "kill him" even though I am playing sister of battle. There where a few other instances of other NPCs making similar mistakes and the sister herself saying stuff wrong, there was even a moment she called Klosterheim a her. but I can't remember specifically what missions they happened on at the moment.
