* In ''The Francis Blake Affair'', one realises once FridgeLogic kicks in that Mortimer [[spoiler:goes after Blake ''before'' he learns that Blake isn't a traitor after all. Mortimer finds £30,000 worth of evidence implying that Blake had sold out - and immediately, without hesitation, goes to find him anyway, since it means Blake is in danger. Either he still doesn't consider the possibility for a moment, or ''he doesn't care'' - a testament to their bond either way.]]
* At the end of ''The Strange Encounter'', Major Macquarrie is posthumously reinstated in the British Army and awarded the Victoria Cross for exceptional bravery and buried with honour.
