I found the answer for the first bonus trivia but before I could work on the second, you published the answer.
Sorry about that. This is just an experimental puzzle to try out another format. Hence, I published the answer early to close out on the draft.
aah! Yes, "JwS" is elegant. Your James Stewart is intrepid so is the "John of the Mountains" or "Father of the National Parks", John Muir, who walked his way to environmental activism and saved Yosemite National Park. I am tempted to round up all the “Walking Johns” and “Walking Stewarts”
No worries. I enjoyed attempting your puzzle filled with words. We have an in-house expert in word puzzles and she used to send our brains on a spin. She has extraordinary talents in many things and owner of a major thread that attracted many ILites like a magnet. This person is a member of an unofficial PR Team for E & PG. If the neighbor's Syrian cat allows her to sleep well in the night, the energy flow will be even higher.
S, Are you serious? The first row gives away the name literally and the second row validates the person.
