But she was just "surface scanning" to see if Garibaldi was telling the truth. In this case, just the truth as he knew it. But someone with Edgars' suspicions and with so much at risk etc, shouldn't have just settled for "I don't remember."

Later on, Lyta was able to see that Garibaldi had "Level 12 Blocks" in his mind. But Lyta was already far more than her original P5 rating by then, even more than a P12 for that matter. Assuming the telepath that Edgars used was also something like a P5, would she have been able to identify artificially-placed blocks/memories, even if she wasn't just surface scanning? Maybe not. But Edgars must have known that Garibaldi disappeared with the Shadow ships, etc, and re-appeared under equally odd circumstances. If nothing else, that should have prompted Edgars to pick someone else. So maybe there should have been some maneuvering that let Garibaldi force his way in, somehow? I dunno. But it just doesn't seem all that credible for Edgars to have basically trusted Garibaldi so easily.

Which supports that she was something of a lower-level telepath, so her disappearance wouldn't raise TOO MANY questions. Wade or someone else on Edgars' staff might have set it up to look like she was "mugged" or something.

It seems that Edgars had arranged for several telepaths to disappear, including the one that scanned Garibaldi and the ones that were used in the lab tests. So they all must have been covered up somehow. Or maybe the lab ones were rogues/"blips." Their disappearance wouldn't have been a big issue. But the one that scanned Garibaldi was apparently "official," she was wearing the Psi Corps badge. Still it would be a lot easier to cover up one, than perhaps a dozen or more.

I don't know that there's any way Edgars could have really found out that Garibaldi's mind had been tampered with. That might have required a high enough level of telepath that they couldn't just disappear afterward. But that's not really an excuse for not addressing it more in the show.

Right, like I said, that's Lyta. She unblocks his memory, after recognizing and telling him "Those are level 12 blocks. Only a Psi Cop can put them in, or remove them." But she's become far more than a P12 thanks to the Vorlons.

That's after Edgars is dead though, and his secrets taken.

Yes, but remember, to Bester, Garibaldi and all the others are just "mundanes."

I think Bester should have been more on Sheridan's side though, because of his pregnant girlfriend in cryo etc. He couldn't have expected Clark to be very helpful there.

It might have taken a couple more episodes to do a decent job of it though, and they were too close to the end of season 4, and what they thought at first was the end of the whole show.

Maybe, but "Intersections in Real Time" could have been skipped entirely - or at least made a lot shorter - to allow for some more time to explain Edgars, Garibaldi, etc.

I meant in terms of story-time used. "Intersections" was largely a waste. At the start of the next episode, he was being drugged/questioned still anyway. It would have been possible to cut out at least half of what is shown in "Intersections" and used the time to better value, such as better explaining why Edgars would trust Garibaldi under the circumstances.

That would have been a cliffhanger season finale, but I don't think JMS has ever said the show would END like that. (Although it would have turned out to BE the end if it had been cancelled at that point.) And remember too, his original plan was for a TEN-YEAR show, with the Shadow War taking up the whole first 5 and spilling over some. He's said/written in some places that the intent was for B5 to be destroyed at the end of season 5, and then in season 6 that's when Babylon 4 (re-)appears to take its place.

Yes, I've said on many occasions in the past, I think events that "conspired against" JMS actually ended up basically forcing him to make the show tighter and better than it would have been if he'd followed his original plan.
