Rick Riordan answered 81 questions, so I'm only going to do the most relevant questions or super short ones. You can read the rest HERE

Some of the answers contain SPOILERS so please read them all at your own risk.

What made you want to add a gay character into the Percy Jackson series? What inspired you to write the series?
Well, same reason I have tall characters, short characters, blond characters, LD characters and POC characters. There are all kinds of kids in life, and they deserve to see themselves represented in stories! For a longer answer, check my website here.

Can you give us a little taste of what Loki will be like in Magnus Chase?
Hint: He's not Tom Hiddleston.

Will you write another percy jackson book one day? You left us with some cliffhangers
Me? Cliffhangers? You must have confused me with some other author

Favourite Harry Potter movie?
I gave up on the movies after Goblet of Fire. I just prefer the books so much more. I liked Prisoner of Azkaban best, both as book and movie. Remus is my favorite character.

Will we ever know who Reyna ends up with?
Reyna is asking me that same question.

Have you ever been recognized in public by a fan?
Yes. Once I had to autograph a receipt on the back of a box of frozen egg rolls in the freezer aisle at Costco.

I have 2 questions. 1. Clarification: Are Annabeth & Magnus cousins? 2. After Leo flies off with Calypso at the end of The Blood of Olympus, does he ever get back to Jason and Piper?
1. Yes. 2. Wait and see.

Why did you write Percy Jackson & The Olympians for middle grade? I think, the concept has so much potential for Young Adult or Adult writing- don't you think so?
Same reason I taught middle school and not high school -- it's just what I do best, and where I connect with readers the most. (also, I am a big middle schooler at heart.)

Won't the Kane Chronicles have an adaptation (movie-series-something)? It's my fav saga and I'm sure it would be easier to put on screens than Percy Jackson and his 10 books. I would also like to know if you are planing to release (at some point) a book with the short stories that mixes both Greek and Egyptian worlds. -btw, I apologize if my English is not the best-
After the PJO experience, you'll excuse me if I'm not anxious to deal with Hollywood again. I have refused all offers on Kane. If the perfect situation comes along, maybe, but I am not holding my breath.

(SCREECHING AT HIM HOLDING ONTO TO THOSE RIGHTS lmao save da series uncle rick)

What's the weirdest fan encounter you've ever had?
Most fan encounters are really sweet. I met a fan once who burst out sobbing and could not be consoled. I felt kinda bad about that. I think she was just glad to meet me . . . I hope. I wasn't wearing a scary costume or anything.

What other mythologies do you like, other than Norse, Egyptian and Greek? (P.s I love Norse and Greek mythology so much)
I just love mythology. Hindu, Japanese, Aztec, Ashanti. It's all cool.

Do you think Frigga and Freyja are the same goddess?
No. The Edda (source material) is pretty clear that they are different goddesses.

In Percy Jackson and the Olympians, you spell Mother Earth's name "Gaia". Then, in the Heroes of Olympus it's "Gaea". Is there any specific reason why you switched?
I felt like it.

When does The Son of Sobek, The Staff of Serapis, and The Crown of Ptolemy take place?
After Blood of Olympus.

Hello sir, I would like to ask you two questions concerning your series with Percy Jackson. One: who do you like better, Percy Jackson or Jason Grace, and why? Secondly, did this influence you not putting Percy Jackson as the main hero in the "Heroes of Olympus" series? Thank you for your time, and I eagerly await "The Sword of Summer" this October! Respectfully yours, Joseph Johnston
Really not fair to compare Jason to Percy. Obviously everybody will choose Percy because he's had his own series. Same with the point of view in Heroes. It's about seven different characters. That's the whole point of the story. It would make no sense to have it be 100% about Percy all from his POV. I've already written a series like that, PJO. Heroes was meant to be something different.

Will Percy come out in your newest book, The Sword of Summer?
No. It's about this other guy, Magnus Chase.

Have you considered writing a series in which the main hero is a girl? You write wonderful female characters, but they are usually part of the supporting cast (we all know it's really about Percy, even though we love the others, too) or share the spotlight (Sadie Kane).
Confession: I'm a guy, so I tend to relate to main characters who are guys. I love my badass girl characters, but I don't know if I would ever write a completely girl-centered POV because, well, I'm a guy.

Sir I want to know from where did you get the Greek name for Percy's sword ANAKLUSMOS? Did you come up with it yourself or does this name has got an entire myth history behind it?
I asked a professor of Ancient Greek to help me with that. He said there is no surviving example of the word 'riptide' in Ancient Greek, but his guess was 'anaklusmos,' so we went with that.

Is Yggdrasil (The Tree of Life) going to play a significant role in your new series?
Check the cover of Sword of Summer. :D

Hello Mr. Riordan, I am a huge fan of your Percy Jackson books. I've even made up a character named Liesel Jackson but her full name is Elisabeth Marie Jackson. Okay, the point is that I have a question. Which Percy Jackson book did you enjoy writing most? Why?
They were all enjoyable but all difficult. I guess my favorite was The Last Olympian because I got to wrap everything up.

was ethan nakamura in love with luke castellan?
No, that wasn't out of left field at all. Where did you get that idea?

What was your inspiration for Magnus Chase and the Gods of Asgard?
Love, love Norse mythology ever since I was a kid. It's what turned me into a reader. I've had the idea for Magnus for almost ten years.
