[Utsuro no Hako]

There is something odd about the hospital scene.

Spoiler:

The last we see of Kanba before the flashback, he's leaning against the wall listening to Yuri. Then at the end of the episode, we see him asleep in pretty much the same position. And we know from Shouma's statement earlier that they aren't in Tokyo, so it's unlikely he rode a train to the city and back during the course of the flashbacks. I see two possible explanations:

A) It's a continuity error, or maybe they left out the flashback signal.

B) Sanetoshi and Himari aren't in reality anymore and Kanba is able to visit them in his dreams.
