Okay, the full text is out and I have checked what the Japanese fans think it means so I’m gonna re-translate Kanaki and Touka’s talk (about Hide).

-The two of them are hiding in an old building-

Kaneki: I wonder if everyone was able to properly hide themselves. I hope we can meet up with them soon…

Kaneki looks back and sees Touka sitting down, holding her knees.

Kaneki: Touka-chan? … Are you okay?

Touka: … yeah…

Touka: You had a friend, didn’t ya?

Kaneki: Are you talking about Hide?

Touka: … when you missed him, what did you do?

Kaneki: …

Kaneki: Excuse me. (As he sits down next to Touka)

He stares with vacant eyes.

Kaneki: I wasn’t able to do it, even once. If I did… I wouldn’t be able to bear how much I missed him.

Kaneki: … so I’m sorry, I can’t help you.

Kaneki: … Let’s rest… we’re all beaten up.

Touka jumps on top of him and appears to kiss him etc…

-Interpretation-

When Kaneki says that he wasn’t able to see Hide when he missed him, he means that he wanted to but couldn’t because he didn’t want to appear in front of him as a ghoul. Therefore he isn’t able to give Touka any advice about Yoriko.

There is a second meaning- since he thinks that Hide is dead, he’s saying that he can’t see him even if he wants to, and if he wanted to it would mean he would have to die. This makes more sense when you see his vacant expression. It also means that if Touka thinks that Yoriko is dead, he can’t offer up any comfort to her because all he wants to do is die when he thinks about Hide.

This is just my interpretation based on what I think and what the Japanese fans think. As for the TouKen, we’ll just have to wait for next week to see Kaneki’s reaction!
