This episode is very heavily meta-textual. It starts with Moebius (that is, the author/artist) apologizing to his editor about the story drift and assuring him that he totally has a plan for all of this. Also note that the title here is The Uptight Garbage of Moebius.

I captured the other page for the text effects on the bottom panel, where the sentry is standing in front of the caption, partially obscuring it.
