One of the search teams finds a dead body with a cryptic message; it seems to be a link to Sousuke’s past. He later recalls how First Season Crazy Villian called him "Kashim". So finally Sousuke’s mysterious past will be explored in the next episode. One thinks this will probably be good - we can get to know more about him as a character. Also hopefully he can transcend his dark past and build a new future - hopefully with Kaname. I am still surprised at how much the Second Raid has converted me - from merely tolerating the Sousuke-Kaname interactions to positively rooting for them as a couple.
The prostitute who was a Kaname-lookalike was also an interesting plot device. While it might be a tad convenient that she and the shopkeeper that gave Sousuke the bottle of liquor both spoke reasonably good Japanese, it’s not entirely improbable. Hong Kong is a very open economy and a longstanding hub of Northeast Asian trade. It wouldn’t be at all surprising that those who cater to foreign customers would be able to speak a smattering of Japanese and/or Korean. Her appearance served to reinforce how much Sousuke missed Kaname as well as to prep him for the Helmajistan clue by tweaking his guilt at abandoning his mission and comrades-in-arms.
well the prostitute has probably been watching too much Fumoffu and decided to cosplay kaname lolx….
