KT was a female friend of Jean-Luc Picard mentioned in a letter included in the Picard family album, but never seen on-screen.
When her husband died, Picard sent his condolences.
In a letter sent from KT to Picard, she expressed her hope that when he visited London, he would meet at the Barbicon Theatre. She described the current season at the theater as "an interesting one with several newly-discovered works by Pinter."
