Something like this. Loki has been defeated. The scene starts like this.
We see saturn, which zooms in on Titan (the moon) then to Loki in a Dark room.
He is discussing how the army failed with someone we cannot see, and the voice talking to him gets angry saying that Loki basically failed in retrieving the cosmic cube for him, in which Loki reveals he planned on keeping it for himself, and would never let such a genocide craving maniac have possession, then addressing him by name.
Thanos then says he knows Loki did this, and he had the army turn on Loki (if that happens)
He then says something along the lines of "I was only going to use it to retrieve what is mine" (This being the IG in Odin's vault). Thanos demands the exact location of the cube and the situation, and as loki prepares an attack, Thanos does something, an attack or something that really hurts loki, tortures him. Loki doesn't say anything, because the screen cuts, but we assume he told him. The next 5 seconds show a large landscape, with a figure standing, looking out into space. The camera is behind him, and as it zooms in, Earth appears in space (maybe some type of screen) and the camera zooms in and around, so we see a quick glimpse of CGI. Then the camera zooms to Thanos' face, grinning. End
If something like this happens, I will probably cry, honestly, completely cry.
