In this episode (2.19), we find that Talia Winters is a mole for “Bureau 13,” (I think) with an implanted “inner personality” that has just manifested itself.
Later, the captain and officers are discussing how it was a good thing it came out then and not a week or so later–and what they could do to forestall another potential mole. Here’s the dialogue after that point:
(Captain Sheridan)
“Is there anything else we can use to protect ourselves if necessary?”
(Cut to Garibaldi, recalling past conversations with Talia)
(Fragments of Talia’s conversations, in flashback)
“I think I might be having a problem with Ambassador Kosh.”
“. . . and I kept getting these images in my head.”
“. . . it was deliberately provoked.”
(Talia, now speaking to Kosh in flashback)
“What was on that data crystal [the VICAR] gave you?” (“Deathwalker,” ep. 1.9)
(Kosh)
“Reflection. . . Surprise. . . Terror. . . for the future.”
(end of flashback, now Garibaldi answers the Captain)
“There may be something else. Let me investigate. I’ll get back to you.”
And that’s it. The episode ends with Lyta speaking to Kosh, telling him that she has to leave, but she’d like to see him once more–at which point we see his suit open and here the foreshadowing flapping of–could it be–wings?
But nothing on Garibaldi’s “investigation,” and I don’t recall any follow-up on it. Apparently it gave Garibaldi some idea, but I must have missed something. Talia was history by that point–much to the dismay of Ivanova (and all us guys that were hoping for a lot more.:D)
And, unrelated to the question at hand, in this episode (I think it’s this one), De’Lenn is heard speaking into a recording device saying something to the effect of “I don’t think we’ll be able to finish this treaty with the Lumati.” Apparently she wasn’t willing to perform those various “Acts of Sacrifice” that Ivanova did episode 2.12. (And just what was that present???)
