[couldn't help it... had to upload a pic of the pair i'm obsessed with for the past months...]
I know most people are probably into the whole Levi/Eren pair but i definitely find Irwin/Levi a lot more attractive. I think they have a more complex bond in that they can, as individuals, hold their own ground but also have a need and dependence on each other. Perhaps its a personal bias but i find the appeal in that Irwin always knows what decisions he needs to make as a commander (no matter how difficult or how many lives he has to send to their deaths) and he already has put himself in the mindset that everyone is expendable (there would be no gain to those who are not willing to sacrifice), however, i think when it comes down to it, Levi is definitely not one he's willing to see as dispensable. Of course he can always play it off as that "as an unbias judgement as a commander", Levi is worth thousands of men just by sheer strength as a soldier (humanity's greatest right?), but the bottom line truth is that regardless of the politics, he will definitely not sacrifice Levi no matter the gain. Even if the "right" decision for him is to be the good commander and soldier, even if the "right" decision is to sacrifice whatever or whoever is necessary for the greater good of the mankind, i really think his love for his corporal is much more important to him and the only time he would go against his values of making the "right" choice.
