Can you steer me towards the passages that deal with that? I don't recall it, and my search has come up dry.If you read 50 Year Mission, there are stories about cast members, not Mulgrew, who also mistreated Ryan onnset. They are Unnamed, but Braga said he gave that actor dialogue about treating people with respect, directed at Seven of Nine in the episode, but meant for the actor.
By process of elimination: Roxann Dawson.
The only thing close I could find was Garrett Wang talking about Brannon injecting commentary towards him (and RDM and Beltran) getting a bit fatter at one point, and then goes on to say that the writers had Janeway teaching Seven a lesson it was them telling Kate how to treat Jeri.
