I’ve been re-watching the Whedonverse series “Angel” recently and have a question about what ever became of the Powers That Be and their Visions-o -gram messages that they sent to Angel through first Doyle and then Cordelia. In season 4 Cordelia when she comes back from being a higher being, she has horrible vision of the Beast etc, then she becomes taken over by Jasmine, goes into a coma, and dies in Season 5. What happened to the visions after that? Did Angel get any visions after that? Please help a confused viewer.
Angel mentions getting one vision in the very last episode, IIRC - that the PTB showed him the biggest baddest Wolfram & Hart clients in Los Angeles - the Circle of the Black Thorn, and that he has to go undercover to destroy them. To do this, he ‘took credit’ for Illyria infecting Fred, because as any good league of evil should, the Circle required that you off one of your own underlings to prove your worthiness. 
Does that help?
Skip implied pretty heavily that everything the “Powers that Be” put Angel through was really Jasmine’s machinations to allow for her own birth (the visions, Connor’s birth, everything). He didn’t have much of a chance to explain before Wesley shot him in the head like the badass he is. Anyway, in S5, Cordelia woke up because the other Powers realized she got a pretty shitty deal. She was allowed to tell everybody goodbye, and then she kissed Angel, gifting him with one final vision. That’s the one that’s revealed in the final episode. The implication being that Angel was always aware of what would happen to Fred/Illyria (and presumably he was also aware of the Connor/Saljean situation, but it’s difficult to say and they never really make it clear).
Not just Angel. Skip claims that all the major events in Wesley, Cordelia, Gunn, , Fred, & Lorne’s lives were similarly manipulated. Though it seems less necessary in the latter three cases, I think Jasmine was screwing around with and Wes from the get-go as well; and I wouldn’t be surprised if she were ultimately behind Doyle’s death, Angel’s 24-hours-of-humanity in hte first season, and the magic snowstorm in “Amends.”
Part of me thinks that the crew’s incredibly ill-thought decision to accept the Senior Partners’ offer was motivated by their realization that they’d been marionettes all that time. This is, of course, assuming that Wesley et al had made their decisions before the amnesia whammy hit.
To your other point, about Angel knowing what would happen to Fred: I disagree. The dialogue in the teaser of the last episode, when he explains his seeming turn darkness, makes it clear that he did not know Fred was going to die. And if he’d known about it, he’d have marched from his office to the lab and killed Knox without a word.
I had the impression Angel made the decision on everyone’s behalf without, you know, consulting with them.
Well, thta was true in the sense that he folded Angel Investigations into Wolfram & Hart. But that wouldn’t necessarily be binding on the others; they could have quit rather than work for W&H. And I think Angel says that he is definitely going to do it whether they come with him or not.
Angel doesn’t say “I’m going to do it whether you come or not.” Angel said “It’s done, so tough shit.” But to be fair, when they were all being shown around the offices, they seemed pretty happy to be there. And they all made the choice to get into the limo that would take them to their own deaths–which was kind of like giving their consent to anything that happened after that (a fact they acknowledged).
I think his exact words are “It’s done. Executive decision.”
Which still doesn’t mean they were bound by it. I seriously doubt any of htem had any contract (mortal or otherwise) with Angel Investigations; they weren’t bound by his decision as individuals. But despite Wes, Cordy, & Gunn tried to do in the second season (and what Gunn & Fred tried between the third & fourth), Angel Investigations was pretty much identical with Angel. The firm, what that name, was done (though Wes & the others could have made a go of it on their own if they abandoned the name, Wes having become a genuine badass by that point).
