[Hijikata has reached a point where the horror is so overwhelming that he's actually staying calm. All his feelings seem muted, which is probably for the best, because otherwise he might just yell and scream about the sheer awfulness of it all, and him having a temper outburst would be an ill repayment to Hange for patiently explaining all these painful things to him.

The prospect of people being turned into titans as punishment is so beyond the pale, if anything his anti-Marleyan sentiment would be multiplying right now if he had a concept of Marley. As it is, the identity of the Eldians' enemy is still pretty diffuse to him. Speaking of enemies, though...]

Does that mean that Reiner and his allies are Eldians too? But they grew up in enemy territory? I see.

[That makes their motivation in attacking the walled city more understandable, but doesn't change much for him at this point. He's looking at a much larger scale of fucked-up-ness now.]

Can regular titans be turned back into humans in any way other than eating a titan shifter? What makes the shifters different from the others, anyway? Is it just a chance mutation that allows some people to turn back?

[He increasingly feels like he should give Hange a break from his questions already. He sure has a knack for inadvertently ruining people's happy leisure time days!]
