Mojovision - S2-E11
Continuity mistake: When Mojo first starts talking to Cyclops through the television screen, Jean is standing next to Cyclops on his right. She then disappears and reappears for the next several shots, and when Mojo is telling Cyclops that he's offering the X-Men a lifetime television contract, she walks up to Cyclops.
