SHERIDAN: You know, I was just thinking about the timing of that evacuation at Z'Ha'Dum. And then I remembered what lvanova told me, that when the three of you went to Z'Ha'Dum to find me, the Shadows picked up on your telepathic signal. Now, those sensors were probably left behind when the Shadows went away. If someone who knew they were there began sending a telepathic probe the moment we hit hyperspace, it might just be enough to set off the destruct sequence. Of course, it would take a very powerful telepath to send a signal that far ahead.
LYTA: Hyperspace has been known to enhance telepathic abilities.
SHERIDAN: Not that much. And do all that and keep Bester from picking up the signal? That's a bit much for a P5, wouldn't you say? Maybe even beyond a P10 or a P12. Now, what I haven't figured out yet is why would someone go through all that?
LYTA: Theoretically? Maybe because he got me angry. Maybe because there's leftover commands from the Vorlons I haven't recognized yet. Maybe because what's left on Z'Ha'Dum can't fall into anyone's hands for any reason. And maybe, maybe because he hurt so many of my people, he deserves to be hurt in response. He has sent away so many loved ones, he deserves to find out how it feels to lose someone he cares about.
SHERIDAN: And I wouldn't have been told because he could scan me. But not you.
LYTA: Yes. Well, theoretically.
SHERIDAN: Well, I'm glad we're talking theory here, Lyta. Because as much as I may agree with your reasons, might even have supported the decision, if this were to happen again, if a command-level decision were made without consulting me, I would turn you over to the Psi Corps and let them turn you inside out. Am I perfectly crystal clear?
LYTA: Yes, sir.
