⚠️Possible Spoiler for Avengers: Infinity War⚠️ In the recent trailer, we can see that Thor is getting tortured by Thanos. Loki is there too, but being threatened by Proxima Midnight’s Spear. Many have assumed that Loki betrayed Thor by giving Thanos the tesseract, but that doesn’t seem very likely... so here’s my theory. This takes place almost immediately after the post credit scene of Thor Ragnarok, Thanos and the Black Order kill a ton of Asguardians leaving Thor and Loki beat down. Thanos remembers Loki and is mad at him for breaking his trust with the tesseract in the first Avengers movie. Loki doesn’t want Thor to die, so he hands over the tesseract. Thanos then orders Proxima to kill Loki, and he forces Thor to watch. Now I know this is dark, but Thanos also crushed the tesseract in his hand, so why would Thor still be alive when it looks like Thanos was crushing him? Simply because he is just gripping Thor’s head in order to keep him from looking away. That could explain why Thor was screaming, not just out of physical pain, but emotional pain. Don’t worry if you’re a Loki fan like me, because Doctor Strange has the time gem and could potentially bring him back.
