Re: ADDITIONAL SPOILERS LIKELY IN THIS THREAD
Yeeeeah Legretta/Tear would be my other weakness, actually. Because the letter and the reaction to the letter and the "when you were trusting and starry-eyed I was using you to get back at your brother and then." I swear, it practically writes itself. In short, Y. Y any day of the week.
I could just never get into Tear/Luke, although the strong stoic female/so very adolescent boy matchup has never been one of my favorites, I must admit. And honestly, I felt like the seven thousand metric tons of blatant Guy/Luke subtext were getting in the way of that pairing as much as anything that was happening on Tear's end. Perhaps it's one of those things where the writers really want it to work but they both just have more interesting things going on elsewhere? But I think the game doesn't make you feel like any one pairing's absolutely set in stone, which is cool. The ending, too, is highly malleable.
