Point taken. Counterpoint: it's not part of the Volume's journey. It's a prelude. It's still canon, but the only part of the Adam short that had fed into the volume itself was the last ten seconds.

The part that Yang and Blake referred to when fighting him (the scene of Adam's manipulating her at Forever Fall) was something about him they knew from before. Blake told Yang "I saw someone very dear to me change..." in Volume 3, and so Yang knew that Blake was manipulated. If Blake also told Yang everything in the short, it would have fed into the final fight.
