A character's first appearance becomes noteworthy if the character appears again in a different book. Yes! By definition, that is already more important than a character that never appears ever again! Even if the character dies in the second appearance. That is why the Final Dies template exists!

Also no, "a priest" is not a relevant character to include in the appearances. In fact, no unnamed character is important to be included in the appearances. That is even part of the help page for the comic template. Here.
