Uncanny X-Men #310

"...Show Me the Way to Go Home..."

Scott's bachelor party is underway, but the man of honor is running late.  As he's leaving the mansion, an alert goes off and he finds a holographic image of the day he let his son go into the future being played out in the Danger Room.  Cable had made his way into the mansion so that he could see the day he was abandoned.  He confronts Cyclops about it and the two verbally duke it out until both have an understanding of the other.  As resolution occurs, Sabretooth alerts the men that an intruder is in the Medilab.  The two find the X-Cutioner and take him out as father and son.  Cable then drops Cyclops off at his party with a note stating Cable will be at the wedding.
