===Talia/Lyta===
The station telepath was Lyta Alexander in the pilot. When she was replaced in the series, events in the pilot were used to explain it.
In the series she was replaced by Talia Winters. When Talia left the series, the already planned sleeper in her mind was used to remove her from the series. A similar plot was later used with Garibaldi.
Lyta was reintroduced. Whereas Talia had been secretly enhanced by Jason Ironside, it was revealed that Lyta had been enhanced in the meantime by the Vorlons.
===Ivanova===
When Ivanova left the series, her character was replaced by Lochley.
However, JMS has said that the Lyta's relationship with Byron filled that particular role that Ivanova was going to play.
==Ending year 4==
