Hi there, fellow turian-lovers!
It's been about 4 days of reading for me to catch up with the thread, but I must say that it's been worthwhile, to the extent of laughing to death of these crazy ideas of yours! awesome! Lovely pics, great stories and insights, it really helped to see I wasn't the only one "reading between the lines".
Soo... I had to spread the Garrus-love.
I recall telling a friend of mine about Garrus when ME1 came out, and trying to explain to her how awesome the character was and how much imagination I had to put into the story to see it as an unrequited love of some sorts. She was all 'seems nice, but... huh, not my type'.
Then ME2 came out. Good God. I needed her to play. In fact, I put her right behind the computer for a couple of hours, lead her to the Archangel recruitment mission, and came back later on to see how it went.
My friend: OMFG! Fffff.. That was the most badass and sexy thing I've seen since Leon Kennedy headshooting zombies. It's all clear to me now. Grr... I just want him to tell me to lean on the table with that soft voice of his *insert vicious grin*
Me: Welcome to the club.
Renegade Shepards:Most of you have chosen the 'right' path of doing things or is it just me? I found it most attractive to line up with Garrus doing "not-by-the-book" actions. He threatening Harkin and shooting him was not terrifying at all for me -in fact, I found it sickly appealing

... Huh, am I twisted? =/
Let me present my case: I had encouraged him in ME1 to do whatever necessary to get things done, as I think myself that paperwork and authorities are too crippling when it comes to do major goods. Shepard didn't accomplish her mission by abiding the law, even when you're a Paragon. She always had to delve into subterfuges. A guy like Garrus, concerned with justice and saving lives, could not by any chance become Saren, he would just continue "vigilanteing" in various degrees, which I found great. Gangs and mercenaries aren't innocent people, he was doing the right thing although operating on the fringes of the law. A guy like him couldn't/shouldn't (imo, and just the way I see it, you know, every one has his/her "canon-Garrus") apply for a bureaucratic work in C-Sec, as he used to. Some people need killing, just as Harkin did, and Sidonis, but that's another point that has to be discussed further.
On the other hand, I understand Sidonis is more to him than a mere despicable killer. This former team member betrayed Garrus' unit, but he acknowledges it and feels truly repentant. It's not the same as if he killed them on purpose and out of anger or rage or whatever, he was forced into it. Some people need killing, true -I still support that-, but it doesn't apply to most of the sceneries in which somebody commits a terrible mistake. Myself, I would spare him, now that I see it that way (thanks to you, guys =) ). Garrus would too, with a bit of help from Shepard, and became in peace with himself. My only concern is that he'll go *all* Paragon after that, being myself quite a fan of pissing off bad guys and scaring people that deserve it. I'd go all good-bad cops with the poor fellow that came across our way.
Shepard: You choose *gently grabbing the merc's shoulder*, either you tell us what we need to know, or this big scarred turian with a rifle will blow your head off.
Garrus: *says nothing. Looks cool and menacing while leaning on a nearby wall, slightly showing his fangs*
Random Merc: *stares at both of them in despair*
Shepard: Now, let's be on good terms and hand over the intel, alright?
Garrus: Commander, maybe he will be more enthusiastic if I shoot him somewhere dispensable. Your call.
Merc: W-wait! I'll talk!
Sorry for the wall of text. I have many ideas that I would like to share, and I think this is a hell of a nice community, I'm truly amazed by the level of kindness and respect it has reached. It's all Garrus' fault! =)
PS: I'm not English, excuse me for any mistakes I might have made :/
