Loki Theory
We all saw Loki try to stab Thanos with his left hand, yeah? Well, Loki is right handed. His clone is left handed. Stick with me here. We saw in Dark World that Loki’s clone could be manhandled and thrown around if he wanted it to be. We all watched him get strangled by Thanos. If that was Loki’s clone then Loki wouldn’t have been dead. To reinforce his “death” the ship was blown up and destroyed. So that, surely, would have killed him. Well, no. I think that as Thanos beamed away, Loki might have hitched a ride. He had to go unnoticed so he might have morphed into a rock or something I guess. So Loki escaped death and found some way to evade Thanos. In the end though... I think the snap killed him. He was fine and dandy, trying to find Thor somehow. Then POOF... Then everything will get fixed and he comes back. So yeah
