Loki vill i början inte ge upp Tesseract. När Thanos frågar honom och Thor först säger han till och med:
"We don't have the Tesseract" and that it was destroyed in the explosion of Asgard (or something along those lines.)
Loki bekräftar inte eller nekar det här, och Thanos säger:
That he's going to kill or maim Thor, and Loki mocks him and says, go ahead.
Thanos fortsätter sedan till:
Torture Thor with the Power Stone. Loki suddenly breaks down, and hands over the Tesseract to Thanos. (Thor is surprised at this, and tells Loki, "You are truly lost, brother".)
Det stoppar dock inte där, för
Loki tries to fool Thanos into convincing him to let Loki join his team, but as he steps closer to the Titan, he tries to kill Thanos with a hidden knife, and Thanos uses the Power Stone to stop him.
Följande förklaras inte i filmen, men baserat på händelsens följd är min uppfattning att det här händer i Lokis sinne:
Loki gave up the Space Stone to stop Thor from getting tortured further. But he doesn't want Thanos to get the Space Stone either, and tries to fool Thanos into thinking that he wants to join Thanos' team, and brings up a hidden knife to strike at Thanos. But Thanos somehow sees this and stops him with the Power Stone.
