If that's the case, shouldn't I think about Miranda, who actually saved me? What about one of the squaddies who pulled me up from the shuttle in the galactic core?
Liara, of course, has a different reason for it: Being forced on us as the love interest/bestie.
Honestly, who would want to think about Miranda before they die? Kidding I swear, leave the torches and pitchforks at home.
Jokes aside, she was the one that stated that she wanted a control chip put into Shepard. While I can understand thinking about her if Shep loved her, why on earth should Shep remember the woman that wanted to control him/her like a puppet? I'm supposed to feel more attached to her versus the person that went through a lot of effort to get Shep's body back? A few "oh, I'm sorry" lines doesn't make it any better.
You don't have to like Liara just because the ME team stated she was important to the plot. Any perceptions of being forced at this point is on the player, not the ME team. I don't think the ME team is forcing a player have Liara as a love interest either. If you are referring to her "ninjamance," then I wouldn't sweat it with future games. They addressed that with DA2 with the heart icon, and I can see the ME team employing the same system down the road.
The flashback could mean, "Good, I don't have to deal with her anymore." It doesn't have to be taken as a warm and fuzzy moment.
You also don't have to do Liar of the Shadow Broker either. For the most part, the player can ignore her all they like, and their game won't be affected by that.
I didn't think they were "forcing" us to have her as our "bestie" anymore than Garrus was "forced" upon us. YMMV of course, so please don't think I'm giving you a hard time.
Anyway, Garrus treats you like you're his greatest friend even if you're a jackass to him. How is that not "forced" in your eyes? When it comes to Liara recovering the body, it makes the most sense story wise whether one wants to believe it or not. She was really the only one had the means and the resources to know where the remains of the body was to hire Cerebus to recreate Shep. She knows that the only way to stop the Reapers was to get the one person capable to getting the job done back to life.
I'd advise ignoring the EU (where she is pretty prominent) and let the rest of it slide. It'll save you a lot of stress.
Besides, I thought that the "Project Lazarus" excuse was pretty thin to begin with. If anything, I felt forced to work with a group that my Paragon Shep didn't want anything to do with. Because...plot.
