This episode is called “Life is But a Dream”, which may not come from the most sophisticated or subtle song, but does manage to encapsulate the lives of Harima Mika and Yagiri Seiji. Considering everything these two have been through, having an ordinary life where they can go see movies and eat sushi together must feel like a dream. Too bad for Mika, then, that Namie isn’t done trying to wake her beloved brother up from that dream, and turn Mika’s into a nightmare.
This episode also focuses in on the Namie-Seiji-Mika triangle that wasn’t really visited in the Shou cour, telling a relatively self-contained story that nonetheless depends on little assists from the rest of Durarara!!’s sprawling cast who are periphery this week. With Izaya in the hospital and his sisters feeding her good intelligence about her brother and Mika, Namie decides the time is right to lure Mika into another dark warehouse where she can rid herself of her once and for all.
What neither Namie, nor I, expected was for Mika to put up such a good fight. Not only is she more athletic than either of us thought, she’s a lot shrewder, self-aware, and well, abnormal, to the point that Namie accepts her as a worthy rival rather than just trash. She ends up on top of Mika and is about to pour acid on her face, but Mika is able to keep her distracted long enough (by reciting all the secrets of the show, the protection of which keeps everything status quo) so that Seiji can figure out where Mika is, rescue her, then give Namie a calming not-kiss and scold her for “going too far.”
The status quo is maintained, Seiji and Mika remain an item, and Namie is appeased by the not-kiss for the time being. But both Namie and Seiji (and we) are also now more aware of what kind of person Mika is: the kind of person who would eat Celty’s head if it meant being able to stay by Seiji’s side.
