My brain... it hurts.

This might be the only chapter discussion where I read all the replies. Because the amount of things I haven't understand is just too damn high.

1-) How were the mindless titants creared? By Ymir? Were they normal people too? Can coordinate do the same? And when did humanity manage to create a serum with same effect?

2-) How did Marley's agents learn about the Grisha's life? Didn't they just turned him into a titan and release to Paradi Island? Even if they knew about him being transformed into a human again (with shifting ability of course), how did they guess he got the coordinate?

3-) How does Zeke have  power to controll mindless titans? Isn't it specific to coordinate? And can't he just control the titans inside the walls?
