"Eh? But a weapon-partner is like a partner for life, right? I don't want something like that." Because people had the bad habit of dying around him and because the ghosts of Franz and Hanna still kept haunting his idea of romantic relationships on the battlefield. He hadn't seen them since the beginning of the battle of Trost, but Eren had asked about the fates of the rest of the 104th trainee squad's members afterward when he had gotten the chance and hearing that half of the couple died had been quite a shock. It had hit him like a fist in the guts just as like the news of Marco's death had, just for different reasons. He had not really been 'that' close with them (Eren was rarely ever 'that' close with anyone except Armin and Mikasa), but he did remember their embarrassed reaction to his complaints about them acting like a married couple only hours before death and the titans had severed their paths for good.

No, no matter what anybody said, he didn't want to be that close to anybody as long as they were still regularly heading out onto a battlefield.
