The lab receives a letter from Suzuha a few hours later thanks to The Slow Path. The time machine hadn't been fixed properly; Suzuha suffered a concussion upon arriving in 1975 and didn't remember her mission until 2000. In the letter Suzuha begs Rintaro to prevent the damage to the time machine from happening, so that she can go to 1975 earlier. Rintaro finds out a few moments later that after writing the letter, Suzuha committed suicide out of Amnesiac Dissonance. Rintaro sends a d-mail to the past as Suzuha requests, but as Mayuri points out, this will totally negate the dear friendship they had all formed with Suzuha.
- Shippai shita, Shippai shita, Shippai shita, Shippai shita! And the line scrawled down the page at the end.
- The dub version is just as devastating.
Suzuha: I failed. I failed. I failed. I failed. I failed. I failed. I failed...
- Despite undoing their friendship, it turns out that the d-mail worked.
