He returned to Trek in one of the most memorable and repeatable of allTNGepisodes , " Darmok . " He ’s a Tamarian captain , and Tamarians only pass along through allegory . A shaky premise , but a wondrous episode , as he and Picard face a vicious beast together and had to learn how to talk to each other . “Darmok and Jilad at Tinagra,“is the struggle they fought , and we got more expectant inverted comma like"Temba , his arms open,“and"Shaka , when the wall fell,“before Winfield ’s fibre , Dathon , was killed .

She then played Mirasta Yale , a Malcorian astronomer who was thrilled to discovery that extraterrestrial life existed when a " First Contact " mission from Riker went cockeyed . When her planet ’s drawing card admitted they were n’t ready for true contact , she left with the enterprisingness .

She donned Romulan ears once more as Commander Torth in " Face of the Enemy , " the sequence where Troi was kidnapped and altered to face Romulan .
She move over toVoyagernext , double playing Mrs. Templeton , a character in one of Janeway ’s lamer holo - novels . She was always a foil for Janeway , and made the stories featuring Lord Burleigh slightly more palatable with her sharp interpreter and withering aspect .
