I've tagged this as a spoiler to err on the side of caution, since this seems to be based on an important shot from episode 5. However, it doesn't really reveal anything about the episode, so this may not be a spoiler.

KF2 official Twitter posted the scnene before ep. 5 was aired, so I don't think the illust itself is a spoiler. But the commentary could still be a spoiler anyway.
