I really respect that when agatha christie wrote her sherlock holmes ripoff (affectionate) with poirot and gave him his own watson with hastings she didn't simply stop at the "detective and his associate/bestie/roommate" parallel but also decided to make them just as sickenly codependent and possibly in love as holmes and watson. 10/10. no notes. she even gave them a fake death that leaves the other inconsolable.
