How these two moments in the story relate
Why These Connect

"The identification of the Metebelis Three crystal (Ep. 21) is explicitly recalled when the Doctor describes his vision of an old teacher in the crystal (Ep. 22), linking the two episodes thematically."

Why This Matters Across Episodes
The longer arc this connection carries
The Doctor's later revelation about the crystal's visions and his spiritual teacher directly references the earlier identification of the artifact, creating a callback that ties the mystery together.
