At this point, you can see the state of shock and hope on Widow’s face after she sees this, giving her hope she can bring back her snapped away comrades and loved ones. The camera then pans over to Thor (Chris Hemsworth) who is seen laying back in his chair with an annoyed/irritated look on his face. This is due to the anger he is feeling from failing to stop Thanos in the previous movie. At this moment he’s probably recollecting the scene from the previous movie where Thanos whispers to him as he, Thor, has his ax buried in his chest “you should’ve gone for the head”. Thanos then snaps away half the universe putting all the guilt on Thor being the universe’s final hope. During this shot, he says nothing as we hear Dr. Bruce Banner (Mark Ruffalo) in the background saying they’d be going in short-handed if they were to attempt to take him down, with a worried look on his face.
