So, let's try to analyze the preview pic.



- Looks like it's still snowy.

- It's still nighttime as in one of the panels below it looks dark outside of the window.

- Yukio is still in his uniform.

- His mouth in the first panel looks parted as he's speaking but in the second panel there's no one next to him so I assume it's probably just parted cause he's "breathing"?

- In this case, he's just processing something in his mind. I have a little doubt about this part because thoughts are not usually expressed in balloons. The only other explanation is that he's reminiscing the words of someone else.

- He boards a subway (?).

- It looks like he takes a seat and starts (as Kittykat pointed out) processing something quite important.

- Imo he doesn't look so "shocked".



Aside this, I was thinking: the only thing we can get by the pic is that he's taking a subway to go somewhere. Now, the fact that he's using a subway and not a train or a plane it means it must be somewhere not too far from where the Cyclop's accident happened. So somewhere in Tokyo. But the fact he's traveling by subway makes me think it has to be some place he can't access with one of his keys. So it's nothing Order related? Ok, these are my thoughts so far. Sorry, just felt like sharing them.
