In addition to his lie that Lisa has never said anything about Freddie and, as I commented on last night, his claim that he never runs from one person to another to spread gossip, even though he could (which he promptly did within the hour, amongst all the other examples of him doing so this series)....
Charlie's indignation"he doesn't smoke, he's taken it to barter with, that's unfair, he's taken it from people.... You should [say something to him], he's taking it away from people who don't smoke [sic], that's unfair"
Charlie's lieFreddie: "Outside, earlier, you were like, 'Oh I can't believe Marcus took that, blah blah blah"
Charlie: "When?"
F: "Just outside..just now"
C: "What did I say? What did I say?
F: "You said.."
C: "I said, don't worry about it Bea, I dunno why he's took it....<snip>...don't get me involved in this"
So even though the 2nd vid refers to another conversation, the fact remains that Charlie is angrily claiming [whilst Marcus is in the room] that he said no such thing about Marcus when he clearly did.
