Why This Matters Across Episodes
The longer arc this connection carries
Barbara’s proactive curiosity in Episode 1 drives the plot into Episode 2. Her argument with Ian about investigating Susan’s background leads to their physical and psychological journey into the TARDIS, making her the impetus for their departure from Earth and entry into the series’ sci-fi framework.
