The final moment in "Crisis", of Lionel preparing to kill himself, was also added at the last minute. John Glover and the crew filmed the scene during the filming of "Memoria", which occurred a week before "Crisis" was going to air. While filming, Greg Beeman, James Marshall and Miles Millar were all sitting behind the monitors, trying to come up with the cliffhanger ending that was going to be attached to "Crisis". Beeman added the moment where the phone rings, interrupting Lionel from completing his suicide; this was used as the opening for "Legacy" and it all eventually set up Lionel's terminal liver disease. Another late change, though it was not at the last minute, came for Lionel's physical appearance on the show. John Glover came up with the idea of cutting Lionel's hair for the season finale. Glover was busy preparing for a play that he was going to be acting in, and he needed his hair cut for the part. Glover made the suggestion while the crew was filming "Memoria", as well as the idea of setting the scene in prison. Gough admits to needing some kind of device to cut back to while all of the other cliffhangers are occurring—Clark being taken away, the Kryptonian symbol burned into field on the Kent farm, and Lex being poisoned—and he felt that Glover's suggestion would help them pull off the effect they wanted.
