Needless to say, the sudden appearance of Moeka Kiryuu puts Okabe on edge, and even if this is not the same world line in which she killed Mayushii, he suspects she’s still a “Rounder”, and cannot fully trust her. Suzu can tell almost immediately that Moeka is someone Okabe knows (or knew), even if he won’t come out and say it. Nevertheless, Okabe assents to Daru’s hiring of Moeka in order to find the lost girl.
Meanwhile, Hiyajou can tell that Okabe hasn’t been answering Amakurisu’s calls, and feels partially responsible for telling him that Kurisu he knows is dead, even if a part of her is jealous that he was so much closer to her. With Leskinen’s unsolicited blessing she strikes out into Akiba to meet with Okabe, but suddenly feels extremely paranoid about being followed.
The camera angles, editing, and music all conspire to make us really feel that paranoia, initially brought on by the sudden appearance of Moeka and only intensified here. By the time Hiyajou is calling Okabe in a near-panic, and he runs out to find her dropped bag, I truly feared for the worst, as he did.
Mercifully (though also a bit disappointingly) the person initiating contact with Hiyajou turns out to be Professor Judy Reyes, a colleague at her university. While communicating in English Okabe fails to correct Reyes’ assertion that he’s Hiyajou’s boyfriend (though the prospect makes Hiyajou blush).
Once they’re alone, Hiyajou brings up Okabe’s lack of responding to Amakurisu. She’s no dummy (obviously), and can tell Kurisu had an incredibly “large presence” in Okabe’s life; far larger than he lets on.
When she reminds him that Amadeus is merely a system, Okabe tells her he simply needs more time. He’s confused, but that’s because he’s not willing to dismiss Amakurisu out of hand, at least not yet (and with no other alternative).
Okabe (and the episode) finally remember the somewhat urgent call Rukako made to him about a guest of his family’s…he comes to the lab with that guest in tow, and Okabe is shocked to find that guest is a dead ringer for Kurisu. However, he later chalks it up as a coincidence (plenty of blue-eyed redheads with bangs out there, after all).
Rukako informs Okabe that the girl has amnesia, and they’ve simply been calling her “Kana” in lieu of her name. She’s hoping Okabe with all his brainy sciency know-how can find a way to help Kana find her real name, where she came from, and how she lost her memory.
While flattered, Okabe is honest about not being an expert in any of that stuff (even if he knows people who are), but Kana’s identity is quite surreptitiously revealed by Mayushii, who recognizes the oopa that is the only possession of Kana’s that might be a clue.
What’s odd is that the oopa is from a very recent movie, but looks like it’s much older than that. Upon the pointing out of that fact, Kana suddenly collapses, just as Suzuha shows up, and instantly recognizes the girl for Kagari, the girl she lost. Well, now she’s found. What’s next; and is it merely a coincidence that she so closely resembles Kurisu?
