I thought it would be fine if I just told you I was taking Eren somewhere. They explained the location beforehand and how it would be necessary to weigh ourselves down, and it sounded like too much trouble for someone who already needs extra support on one of those legs..

[Levi is right though, they should have simply told him the truth rather than attempt to avoid it. But it had come from a place of misguided worry and empathy, not wanting to hurt his feelings (so much for that) and not wanting to say no when he inevitably asked to go.]

Even without weights it must have put extra strain on it, right? I didn't tell you because it sounded too risky, and I didn't want to be forced to lie and say that I didn't want you to go with us!

[Because it would have been false, of course Hange would always want Levi to go. Yes, they could have simply ordered him to stay put, but it wouldn't have felt good either. Hange has no qualms about giving orders when it comes to scout business, but using that superiority at a personal level to force Levi into doing something just didn't sit right.]

You can see why I was worried though, right! You told me yourself that you still can't get on the floor to scrub! What if something happened and you couldn't walk on it, and we were days out of the city?
