[Throughout Eren's entire explanation, Rui sits quietly. At first, he nods every few moments to show his attentiveness, but that eventually tapers off. The details of Eren's world are - a lot more horrific than Rui anticipated. He's gone extremely pale himself, sitting very still and feeling cold inside his cozy sweater. The idea of humanity driven into such desperate circumstances - and so many terrible things - it makes his stomach churn. It rattles thoroughly.
Then Eren says, I lost a leg, and Rui goes rigid in his seat, instinctively squeezing Eren's hand and swallowing thickly.
Next Eren is talking about what he is, and what he can do, and Rui feels almost lost, because it's kind of ludicrous. He becomes one of those things? What does that even mean, exactly? This must be why Eren was so worried about Rui himself being inhuman. So it's a worrisome thing, right? Should Rui be very worried, too? Well, he is worried, but in a myriad ways. And he finds that most of all, he's worried for Eren.]
If that's what helped you be okay, [Rui says finally, wide-eyed,] then I'm glad for it.
