Mercy Thompson Series. (Spoilers.)

Alright. Its been bothering me a lot lately. I love this series more than I should admit and I'm honestly considering getting myself a 'Mercy's Garage' hoodie. (Click on the photo if you are interested in buy one.) Though there are a few things I really need to ask and I'm hoping someone can answer them. Which is doubtful, because only the author will know them. (Most likely.) Not to mention I simply need to talk about it, so there my be some spoilers. So, here goes!

Its very difficult to pick a favorite character in the series because they are all so wonderfully complex and interesting. I waver between 3 characters mostly. They are (in no particular order):
Stephan-The Vampire. He likes Scooby Doo. Enough to have his own Mystery Machine, anyway.
Warren- A Werewolf. A Gay Werewolf. With a sweet Texas drawl and a sassy attractive divorce lawyer for a boyfriend, who I also happen to be fond of.
And Ben- Also a Werewolf. Foul mouthed, Blonde, and oh-so-British. I can hear groans from other book readers about this character, I'm sure, but I can't help it.

At this very moment, I'm favoring Ben a little more so than the other two. In Moon Called, Ben is depicted as a woman hater and a possible rapist. (At least, Mercy hadn't dismissed the thought.) He also seemed to have this problem with Warren (as most werewolves do) and his lifestyle. Despite this, He is often partnered with Warren for Pack duties. As a result, in my opinion, they have this odd friendship or understanding.

I wanted to like him from the very instant he was introduced. I was indifferent with his character at first. One minute I found him charming and the next he was an ass. However, as the series has progressed we find that Ben isn't what everyone thinks he is. In fact he's just one big old softy. He just has a hard time showing affection. He was deeply wounded as a child, but once this was revealed I'm sure quite a few people began to understand how Ben worked. It only made me love him more.

I do hope that we get to see more with Ben in later books. I have finally gotten most of my Stephan fix, but I would love to see more of him too. There are a lot of characters that just seem to not get enough limelight. I understand the series is about Mercy, but She has no where near enough interaction with some of the other extraordinary characters in her world. Now, on to the questions!

Last Names: Ben? Warren? Stephan? Does Stephan even have a last name? What do the living favorite members do for a living? (I'm sure this one was mentioned somewhere, I've probably just forgotten.) How old is Ben? How old is Stephan?

The most important question: Will I see more of them all in later books? (Particularly Ben!)
