To me the Titan Shifters Hom eland is full of humans that weregiven that power to protect the humanity and fight the Reiss Family my guess on the subject also would be that maybe there are still Asians that ranaway before the massacre, probably some Ackerman too. And they're actually indiferent about humanity's annihilation since they almost get erased from the earth so they're all like a society that has this serums to defend themselves from titans, the knowledge about the world, the only thing getting on their way is that they don't have the 'Coordinate' power.

I don't know what's with the crazy mind of our dear Isayama san but, he added this character that didn't know which language people speak within the walls (which it means he neither lives with the Titan Shifter folk, he's been kinda isolated),but still he comunicates perfectly with another titans and has a 100% control of he's titan form. . . and as you can see in this image:

seems like he has a big scar in his left arm. AND* he can turn humans into titans... holy crap!

It's like i totally love the Beast titan, but i fear...him a lot.

And now to my point is that, uhm, There's certainly a huge gap between our lovely Teen Titans Mission and Grisha's.

IfGrisha's mission was so direct, he was so free and yet full of information, that probably he wasn't an envoy from the homeland, maybe he was in touch with the Beast titan, a disciple perhaps, and probably the simian titan somehow erased his memory when they found Eren's dad, he... made sure Grisha Yeager could never be able to tell who the Titan Beast was.
