From Michael Avallone's Book:

The last couple of years, information has been brought to the forefront about the lost scene in Friday the 13th Part 3 , where Abel, Chris and Rick meet. One of the first photos of this encounter surfaced in early 2009 in the form of a contact sheet. Since then, savvy Photoshoppers have extracted single frames from the sheet to display for fans. The one question remains, how did the trio's encounter occur and what did they say?Thanks to Michael Avallone's book,, we now know those circumstances. The book was published in 1982 and based on the original shooting script before rewrites and on-set changes affected the final product. Below is an excerpt of the book which details Chris and Rick meeting up with Abel. Rick's character was named Derek in the original draft of the script, so remember that fact when reading the following.
