Did you know that in Thor: Ragnarok?

Did you know that in Thor: Ragnarok?, when Loki transformed into Odin, Thor quickly realized it wasn’t his father? He was so sure that he was about to strike Loki's head with his hammer. But do you know how he figured it out? I'll tell you. Before returning to Asgard, Thor found the Nine Realms completely messed up, which normally never happens when Odin is in charge. When Thor came back to Asgard and saw Odin wearing a bathrobe and eating grapes, he began to question why Odin wasn’t doing anything to fix the chaos in the Nine Realms. In that scene, you can see Loki visibly nervous and starting to tremble his hands, something he learned from his mother and that he also used to do when he was upset or nervous. Thor knew Loki so well that that small hand movement was enough for him to know that the person there was actually his brother. Loki didn’t even try to hide it; he messed up the Nine Realms and thought his brother wouldn’t notice. If it had been Odin, he could have stopped the hammer without difficulty.
