I’ve been watching TNG for the first time and so far season 1 has been hit or miss. Ether a episode will be really good or really bad. So far I think episode 23 is a really good episode! I hope that Tasha isn’t actually dead. I liked her and thought she was a gorgeous woman! This is the one and only time I will ever want spoilers but is she fully dead or does she return?
To keep it vague, many actors who liked working on Trek and who the show staff liked working with would often come back as either other characters or their popular characters via various means (time travel eps, dreams, etc). Tasha’s actress does make several reappearances and Tasha’s story does get some continuation/wrap-up story wise (to effect the character is not forgotten by the other characters or the writers after she dies), but the actress never rejoins the cast as a full-time regular.
