So we were ( at least marvel fans ) waiting for the last infinity stone to appear in Black Panther. Thor 3 was supposed to reveal the last stone but Marvel changed its plot and removed the stone from it.
After this, everyone was having an eye on black panther to see the last stone. But again, Marvel did not show the last stone in it. Yes, you read that right, the stone is not in this movie.
I was already expecting this because I think this last stone will be revealed in Avengers 4. Avengers 3: Infinity War will end without it, to keep the story continue.
