Also, here is the first time you begin to realize that Londo is suffering from dimentia. I mean SERIOUSLY. You can choose one wife of three: An ugly bitch who hates you, an even uglier bitch who hates you even more and is even MORE ambitious than you; and a hot chick with a great body and lips that obviously want to encompase cylindrical objects who wants to please you as much as she can.
As for Talia, I prefer her to Lyta, I think Andrea Thompson is a much better actress than Pat Tallman.
Yes, the station telepath was meant to be an action role, probably including physical fighting.
There is an interview with Claudia Christian somewhere out there, in which she points out (to paraphrase) that Andrea Thompson brought a kind of vulnerable sexuality and helplessness to the role that wasn't there anywhere in the script.
I'm afraid I tend to agree with that assessment.. I find it annoying..
