Oh, yes. Eren just turned 14, so they are quite close in age. He'd probably think of Toushirou as a kid if he saw him first outside of class. Although the way he talks would clue him in, since he's not completely unobservant. And he would adjust his behavior.

So yes, they probably wouldn't get along well. Yes, his views are very terrible. Although I am hoping he'll develop and change them as time passes.

Eren is currently boycotting classes as much as possible! So he'll most likely be getting in trouble for that. I'm sure he'll get hauled in, so they'll have an opportunity to meet.
