Insurgence - S2-E12

Revealing mistake: After Lex's employee walks out of the office, Lex's gets mad and throws most of the objects off his desk. Prior to this, we a computer screen displaying something. When the objects go flying off and hit the wall, we see that it wasn't actually a computer screen but a prop that was made look like one. It was just the frame, a piece of paper that served as the display covered by clear plastic to make it look like an actual computer screen.
