Okay I was looking online and found some answers! the ones that are bold were answered by Sylvia Day. The one that is not is just an assumption made.

1) At the end of Bared what did Gideon run back in to Eva's place to grab?
His prescription bottle of sleeping pills

2) What happened in his office when Eva went up there after seeing his ex on the street?
Nathan had made his first visit to Gideon that day. So the lipstick was blood and the furniture was moved around from a scuffle between the two of them. Because well we all know how Gideon gets when it comes to Eva.

3) Who is the doctor that violated Gideon?
It is the Doctorial Candidate, who is not Dr. Lucas (so someone going for their PhD??)

4) Where did the nickname Ace come from?
In Death series by J.D. Robb/Nora Roberts

5) Who was at Gideon's house when she called him from the hospital?
it was his security team

6) Will there be a fourth book?
She has said that it was originally set to be a trilogy but it all depends on how Entwined turns out she wont try and cram everything to just end it but wont draw it out eaither.. so we will all have to wait and see.

7) Why would the Doc lie and say nothing happened to Gideon when he was a child?
I hace come across this as a possible answer... it could be because his father screwed over the Doc who Gideon's mother took him to so it was the Doc's way at getting back to him. It was said in the book how he never knew what type of people he would come across who would want to harm him because of what his father did.

A couple of questions I still have:
1) Why was Corrine there at the building the same day Nathan went to go see Gideon the first time?
2) Will Cary get a book? or his HEA?

Fun fact:
The cover of the US books all have Gideon's accessories and the UK books have Eva's accessories.

I sent a tweet to Sylvia Day and had asked her about when she had said she was going to be doing a section from the first book in Gideon's POV. This was back before RIY came out but here are the tweets:

ME: Just wanted to ask. Did u ever do the part in Gideon's POV? I had totally forgot about it and thought I would ask

SD: Not yet. It's a struggle and I had to put it aside to work on Reflected in You. I won't forget, though, I promise.

ME: Ohh good I thought I missed it! have u thought of doing the books in his POV?

SD: I haven't considered it, no. I can't begin to imagine how long that would take w/Gideon being so stubborn.

But maybe after the end of these he will open up and let her write his POV! but all we can do is wait and see.

Here is an Interview that Sylvia Day did.

I am having a hard time picking who I would pick to play Gideon.. here are the 3...
