Year Out
Beverly takes a year out as head of Starfleet Medical, being temporarily replaced by Dr Katherine Pulaski.
Erase Memory
The one area where Pulaski fares better than Beverly is the mind wipe. In Homeward, Beverly has to tell the captain that because his neural physiology is very unusual, she can't wipe the mind of the unknowing Boraalan who has wandered out of the Holodeck during a Prime Directive damage limitation exercise.
Though the usual job with memory is post-PD contravention erasure, there is one occasion, in Lonely Among Us, where we see the reverse. Beverly's mind has been suppressed by the roaming life form caught out of the energy cloud and then has to be retrieved, in that episode by Troi using hypnosis.
Closed Gates
"I got a call from my agent saying they had decided to go in another direction with the character. That was literally all I heard. I was very surprised. And my fellow cast members were surprised."
"I had incredible support from the fans. When people found out I wasn't going to be on the show, I got tons and tons of letters. They were sending me copies of letters they sent to Paramount, letters they had written to the producers, even petitions. And they kept it up over the whole year. I even had Star Trek fans who flew hundereds of miles to come see me in my play."
