So then I wondered if Selvig is still kind of residually affected by the Tesseract.
Could Loki manipulate Selvig and thereby manipulate the Tesseract? (Selvig is in this Greenwich University scene too)
Of course, this is steering us toward Loki-as-chessmaster territory, and various people associated with the film have commented that Loki was not going to be the villain this time around.
Yeah, Selvig could easily be taken over by Loki again through mind control (as has been shown in previous movies), but the Tesseract is not on earth anymore, so Selvig can't get a hold of it by himself even under Loki's control. In addition Loki doesn't really need Selvig to operate it. The way I see it is if Loki took the Tesseract again (from perhaps Odin's Vault) even if just for a moment, then he has already gotten his hands dirty, so why would he not just use it to create Kurse himself?
