[They're like an old married couple or something. When they're not pissing each other off, it's because they're busy staring into each other's eyes. Has Armin ever seen Eren like this with someone else?]

You said that, yeah. It could be pulling from our subconsciouses as well. We shouldn't rule that out...

Still, I don't think we're the only ones to blame.

[Armin certainly isn't. This is...definitely more a Them(TM) issue than anything else, or so it seems.]

There's no telling who might be pulling the strings. All we can do for now is try to pay attention - see what information we can gather through our experiences.
