Wow, seven new pages appeared since I last checked this thread. xD
I think the blunt way of starting Garrus' romance worked for Shepard #2, but she's been trying to date a turian for years and has just about given up on being subtle. I like to imagine that she had a conversation with Shepard #7, who is much better at this sort of thing than she is and would have told her to try a more "turian" approach. When she did, Garrus still didn't get it at first, but when she got even more blunt about it, and Garrus started to show some interest, she probably would have said something like "Wow, really? Success is mine!" xD I can also see Garrus asking Shepard #7 for advice... and after telling him that bragging about past "relations" to the woman he's interested in is a bad idea, #7 would say that Garrus should be glad #2 didn't really want to spar.
Shepard #7: You really dodged a bullet there, Garrus. The woman fights like a biotic krogan. I'm so proud. *grins* I trained her myself!
For ME3, I think it would be best if all of the surviving squadmates returned (except a few who might not return because they made it sound like defeating the Collectors would be their only mission with Shepard), and if anyone got their squadmates killed off (some accidental, some on purpose) then they obviously shouldn't return. If they add more squadmates, then the option of recruiting them should be available to everyone, even if the people who saved everyone have to choose a certain number of recruitable squadmates because the others won't "fit" on the team (and no choosing between character "counterparts" either - the option to have both Garrus and a female turian and/or Tali and Kal'Reegar should be open if those two characters are recruitable to anyone, possibly at the expense of choosing them over other teammates, like the humans, if the team is limited to a certain number). It would be unfair to everyone who saved their entire squad if there were some characters who were only available to people who didn't save them. My Colonist Sole Survivor Shepard might finally find romance with a female turian if she had the right personality, but killing off his best friend just to give him that chance is cruel, and he would rather have no romance at all than to see another person he cares about die.
I would like another turian (possibly female) and Kal'Reegar (or another male quarian) on my ME3 squad.

Maybe they could make the DLC only characters for ME2 recruitable in ME3 for those of us (myself included) who don't use downloads, but for some reason that might be too much to expect. A few of my Shepards would make some less-likely requests, like romance with the Illusive Man, Aria, or a krogan. I also read an idea somewhere for an elcor battletank. That would be
awesome.
Also, I would rather not have to choose between two (or more) characters I like in a Virmire-type situation. It was fine for Ashley and Kaidan because I don't like Ashley and Kaidan isn't one of my favorites, but for some of my Shepards (#1, for example) to choose between romance interest (Tali, in his case) and best friend (Garrus) is an impossible decision that can only end badly. D: Besides, Colonist Sole Survivor Shepard does not need anymore guilt. A choice between squadmate and large group of people (sacrifice many to save one, or sacrifice a good friend to save many lives) could be interesting, although depending on the squadmate, that large group of people would never stand a chance in most of my playthroughs. Splinter Cell 108's suggestion of a choice between the destruction of homeworlds sounds good too.
I know this post is long... o_o;
