Please tell me Lawrence Olivier has a speaking part here and that you simply forgot to put his lines in! :D
And while he seems to get the concept of "four walls" I'm not sure he gets the fourth wall concept but by his "acting or leaving" comment, he seems to partially grasp it. ;)
All I forgot was a note that this Olivier came from a fascist England alternate reality, had served, and willingly took the jump that the founder of the Yorick Gang made to him. In a time and place like that, you'd learn to keep quiet when you need to - it's pride in his Metaspace skill and the realization that it's currently been taken from him which spurred him to speak.
And the line about the four walls is supposed to say he doesn't have metaconsciousness about the strip or the stories, but it's a bit ambiguous due to the name "Metaverse" - which likely should have been "multiverse" but I thought that was a particular author's term, not a scientific term to theorize universes upon universes, and so I started up a new term in honour of the Meta Gear travel device. Phew! That's a lot of typing for a touchscreen...
