Horace Slughorn, relaxed finally in his own home not roaming no more hiding. He was free to relax, be active, and remember. He was free to have his memory's collection of students. Regulus and Sirius Black appeared and were in front of him, and in his sitting room. They sat down and recollected of the times they had as student and teacher.
Regulus and Sirius left and Slughorn left with his so far sane mind. When out of nowhere Tom Riddle was in his room replacing Sirius and Regulus. They threw threats at each other until Tom started to destroy what sanity that Horace had left. With the flick of an arm, Tom was gone.
As Horace mumbled to himself that it was all in good time that he would die. Not now, but at another time! Yet he started to sit there with Lily and James Potter. Talking, talking about imminent death. When nothing else was left to be said, they hugged and said their goodbyes.
Horace was on the last hinge of a sane mind until his dear friend Severus walked in they spoke to each other of profession, their potions, and what they've accomplished. Finally they said how both lived for a worthy cause they said their greetings to the world of death and Horace and his memories were finally in peace.
