The fact the memory changed as the attack was about to land should have told Shiro that some part of him heard him. Yet as they float there weightlessly, their voices don't so much resound audibly as they are heard in each other's heads. Both a blessing and a curse, as he briefly seems to stop shaking nearly as much. Just as their vision is overtaken by a scene they both knew: the two of them, staring up at a deactivated Black Lion.

It's only a flash, but it is there.
