We open with Gamora and Thanos on a volcanic planet instead of Vormir. Gamora shows Thanos where The Soul Stone supposedly is.
Gamora: Well, here we are. The location of The Soul Stone is right in there. I guess you better go in and get it.
We are then shown where exactly.
Thanos: This is a lake of acid lava.
Gamora: I know, crazy, right?! Well, hop on in and get that stone you need so bad. It's all the way down at the bottom.
Thanos: (uses The Reality Stone) Bubbles.
The lake turns into bubbles.
Gamora: Crap! You and your stinkin' bubbles!
Thanos: You lied to me again.
Gamora: Whaaaaaaaat?! That's crazy! You must have turned it into bubbles. I mean I wouldn't lie to you.
Thanos: (teleports them back to his ship where Nebula is held) Your sister will pay for this.
As soon as they arrive however...
Chitauri: Oh my gosh, Thanos! The sister has escaped!
Thanos: DANGIT, YOU GUYS HAD ONE JOB! (leaves) THIS DOES NOT PUT A SMILE ON MY FACE!
