One of my favourite (slightly crack-ish) headcanons is Erik, shortly after realizing the extent of his feelings for Christine, paying a visit to his Only Friend the Daroga in order to (subtly---he thinks) fish for advice on winning a lady's favour
YES YES YES!!!!
I honestly love everything about Erik going to the Daroga for advice about the ladies!
Just picture, Erik sitting in the parlour, a cup of tea in his hand, dubiously asking around the question of how to woo a woman, and doing his best to get the Daroga to talk about his experience with women. And he thinks he’s being so clever and so careful until Daroga asks him, “who is she?” and Erik chokes on his tea and splutters “no one” but Daroga knows and when Erik calms down he gives him quality advice.
This is basically my own headcanon for any AU where things work out well
