9. Jason always picks his Victims - Friday the 13th Part II
It's indicated that Jason likely saw his mother decapitated by Alice at the end of "Friday the 13th." So before he goes back to Crystal Lake to continue his siege of angry murders against promiscuous campers, he pays a visit to an old friend. After Alice manages to find some normality in her life, she spends her free night picking ice and preparing a drink until she realizes too late her ice pick is nowhere to be found. Jason helps her though by putting the ice pick in a place she won't forget to look. Right through her skull. After Alice, the series never found it necessary to follow-up on all of the surviving characters aside from Tommy, who had potential as Jason's Ahab, but never really appeared again.
