The Family of Blood

[1] It is the second episode of a two-part story written by Paul Cornell adapted from his Doctor Who novel Human Nature (1995), co-plotted with Kate Orman.

In a Doctor Who Magazine interview, Executive Producer Russell T Davies characterised the "Human Nature"/"Family of Blood" two-parter as perhaps being too dark for the programme's audience.

While John Smith struggles to understand what is happening, Timothy Latimer briefly opens the fob watch containing the Tenth Doctor's Time Lord essence.

He pushes the mother into the event horizon of a collapsing galaxy, wraps the father in unbreakable chains, traps their daughter in every mirror in existence, and suspends their son in time before putting him to work as a scarecrow.
