Why This Matters Across Episodes
The longer arc this connection carries
This connection establishes the foundational mystery of the TARDIS and the Doctor, which Ian—initially dismissive in An Unearthly Child—must grapple with in The Cave of Skulls. The police box serves as the linchpin between the mundane world and the Doctor's time-traveling reality.
