Shane could be an individual with a passion for the macabre. In the context of 'Shane telling scary stories', he or she is the storyteller. Maybe Shane grew up hearing scary stories himself or herself and decided to carry on the tradition. He or she might have a collection of age - old tales, or perhaps create their own original scary stories to share with others.
They're not the same. Everett Ross and Thadius Ross have separate identities and storylines in the comics. Their powers, if any, and character arcs are completely different.
One interesting Shane Acker fanfiction could be about exploring the backstories of the characters in his works in more depth. For example, delving into the childhood of a character and how it shaped their actions in the story.
Since I don't have a lot of information about this specific story, it's hard to say exactly who Mike Ross is. He could be an ordinary person with an interesting personal story that involves some sort of growth or change symbolized by 'big boy pants'.
I'm not sure specifically who 'ann b ross' is just from this phrase. It could be an author. Maybe it's someone who has created works within the realm of 'fantastic fiction' which might include elements like magic, otherworldly beings, or extraordinary adventures.
