So how did he command the pure titans to kill the smiling titan then? Maybe it has something to do with Dina being a mindless titan whereas Zeke is a proper shifter. Just guessing here but maybe shifters have a more intimate connection to Ymir due to the Nine apparently being parts of Ymir's soul whereas mindless titans have no will outside of eat & destroy. So Dina might have provided the means to control the titans but had no input in how they acted because of her will being sealed away whereas Zeke is fully conscious as a shifter and can input his will with Ymir apparently favouring her kin over other shifters in situations like this one.
