Jean and Cable must use an amplifying machine to send a message to the X-Men in the past and warn them of coming danger.
Story continued from X-Men #40. In the past, Magneto and Xavier discuss the theoried "homo-superior" in a bar before protecting a crippled performer and partaking in an old fashioned bar fight. In the present, Xavier and Jean Grey get hooked up to a Shi'ar machine that will allow them to channel Cable through time in order to alert the time-lost X-Men to the threat Legion poses to the universe. Back in the past, Cable finds the X-Men and tries to trigger their memories. And, at the hospital, Xavier and Magneto run into Legion, who promises death to Magneto. Continues in Cable #20.
