After watching the Infinity War, there's one thing I can't get. How did Thanos get the Reality Stone? Gamora kills him when he has two stones, and then he appears with the Reality Stone. I watched this scene 5(!) times, but I can't get it.
Reality is often disappointing. That is, it was. Now, reality can be whatever I want.
This dialogue from Thanos, as he reappears after being killed by Gamora, is enough to understand the scene. He has the Reality stone. So he creates a fake reality for Gamora in which she kill him.
