Daru and Maho are hard at work on “Phone Microwave (Temporary) Unit-02”; progress is slow and full of smoky setbacks, but neither party has any intention of giving up anytime soon. Meanwhile, in Mayuri’s words, the “normie life” of Rintarou (who has given up on trying to have both Kurisu and Mayuri in his life, without starting WWIII) is taking off, and he can’t tell how left behind she feels.
Rintarou can’t so much have a conversation with her without checking his buzzing phone. He says things like his going to America is “good for everyone”, even though it’s not good at all for her. She decides not to go eat with him, but ends up encountering Ruka, who calls her Rintarou’s “Orihime-sama”, pertaining to Vega and the heroine of the story upon which the Tanabata festival is based.
While the lovers representing Vega and Altair were banished to opposite ends of the galaxy, once a year a flock of magpies forms a bridge for them to meet. Mayuri, who can tell that Rintarou loved/loves Kurisu and not her, can’t subscribe to Ruka’s assertion, and all Ruka can do is offer a handkerchief to dry Mayuri’s tears.
Rintarou suddenly arrives at the lab while Maho is showering and Daru is unprepared. He’s ready to drag Daru along with him to America, but the trash is full of bananas and there’s a curtain covering the back of the lab. A light dawns in Rintarou’s head, and his initial suspicions are proven right when he pulls a bunch of slimy green ‘nanners from the trash.
When he discovers the new Phone Microwave, he whips himself into a damn frenzy trying to remind Daru just how much torture he endured and who died last time the device was constructed. Eventually his rantings are interrupted by Maho (in a towel, at first), but he soon turns on her, going so far as to call her a murderer if she proceeds. That earns him a much-deserved punch to the face.
Once heads have cooled a bit, Rintarou and Maho debate the “laws of the world” and whether messing with them is “challenging God.” While Maho can appreciate and even respect certain aspects of Rintarou’s theory about how the world works, she doesn’t believe humans would have the ability to make a time machine if they were never meant to.
Rintarou rebuts, telling her how she couldn’t possibly understand what it’s like to fail and fail hundreds and thousands of times, which is laughable to us because we know that the entire time Kurisu was alive, Maho was struggling and failing to reach any of the breakthroughs or earn any of the accolades or gain any of the fame her kohai had. But she never gave up then, and she’s not giving up now, no matter how much Rintarou yells at her.
Rintarou skulks off, and by chance, ends up encountering Mayuri in the park where they used to spend a lot of time before they met Daru. She used to wait for Rintarou just as we saw her wait outside his college in the present. What Rintarou doesn’t know, but eventually finds out as she talks, is that Mayuri heard every word in his rant back at the lab about how saving Kurisu meant killing her off.
She also tearfully notes how much he’s looked like he’s suffered ever since he made the decision, which makes her think he might’ve made the wrong choice. There’s no way he can be okay with how things have turned out if he has that look. His eyes have always betrayed how he actually feels. Rintarou is devastated, and tries to tell Mayuri to do the impossible: “not think about it.” Things aren’t that simple, Okarin. The clouds part, revealing Vega and Altair.
This was an emotional powerhouse of an episode, with clashes between characters of an intensity that’s been mostly missing from this season. With those scenes came brilliant performances from Miyano Mamoru, Hanazawa Kana, Seki Tomokazu and Yahagi Sayuri. Also brilliant is the fact that there are no right or wrong answers.
As Daru and Maho search for that one perfect solution to the formula among an infinite possibilities—for the Steins Gate—they must be cognizant of the fact that they are imperfect, lest the despair Rintarou has already experienced not only return, but worsen.
