The more I hear about the 'Clairvoyant', the more I get the feeling that it's Ultron, or atleast an alpha/beta version of him. If someone or something could get just about any information from a computer, that intelligence should be able to fill in the gaps for any info it is missing. 'Psychics' have been doing this for millenia. But if something happened and the only place it is recorded is in someone's brain, then it would not be accessable to that intelligence. Plus, the ads for the episode had the hashtag of 'everythingisconnected'.
There is still a lot of questions regarding Coulson's ressurection. The obvious one is why Fury was so intent on the ressurection? Why is Coulson so important? A sub one on that, perhaps the initial order really didn't come from Fury, but when the process started and he found out about it, perhaps he let it go in hopes of drawing out who planned it (I'm probably overthinking that one). What happened from the time he died in Avengers until we see him in the 7th surgery, we were led to believe that he was not himself, who/what was he? Also, how did they infact ressurect him? There is probably a few more I'm not thinking of.
As for the show itself, I like it. I think its biggest fault is that it feels a little disconnected from the larger Marvel Universe as a whole. I think it would feel more connected to the Marvel Universe if they maybe included some lesser villains and/or heroes, or atleast if they are going to a certain area, maybe say why X hero can't help. Or maybe make mention of small adventures that even some of the bigger heros had. Nothing that would effect the overall Movie productions, but just enough so it feels a little more connected.
