Great episode but I'm a little confused about a few things:
What is the "1 new RINE message" that Okabe receives as soon as Mayuri and Suzuha escape into the past, and after which he's all "Schrodingers box has opened!"
Why does Okabe say that Leskinen "sought to obtain" the time machine when all they were trying to do is destroy it? Earlier also Leskinen said something along the lines of "what if someone obtained the time machine instead of it being destroyed", but it looks like all he's doing is blowing it up.
Why exactly didn't the time machine get destroyed in this episode?
What does Ruka mean when she says the second dmail of Daru goes to Suzuha "after she departs on her trip". Which trip is this and exactly where is this DMail received? Is it the Dmail suzuha receives in SG0 from a different Daru than the timeline Suzuha came from, talking about Operation arclight? But then what is the "after she departs on her trip" part?
A few confusing and unexplained bits but heh, SG1 was also like this yet was still amazing.
