We really need to cover production blocks better here at Tardis. Do they even have a page? Production block.

Mkay. Adam Mitchell is a guest character in common between those two episodes, but guest character is only rule 3. It passes rule 1 as well, but fails immediately at 2—Dalek was produced in a block with Father's Day, directed by Joe Ahearne. The Long Game was directed by Brian Grant, in the following production block. Those cannot be counted as a two-parter by these suggested rules.
