"A Child's Heart - Part Two" is the 963rd episode of Casualty and the second episode of the 30th series. It was preceded by "A Child's Heart - Part One" and followed by "Objectum Sexual". This episode's opening sequence is different from the others in series 30, as it used a combination of the original 1986 opening with scenes from the previous episode. This was likely due to the fact Charlie's life is on the line in this episode, and it's symbolised by his flashbacks within the episode and in the opening credits.
