It was plot convenient to smash Carla's legs under ruins, so that Smiling titan could eat her in front of Eren, so that Eren was driven by anger and hatred :D

But regarding Grisha, I have this feeling he left for some serious business. If he somehow knew, that the shifters are about to attack, he would go to the place, where Reiss family would be hiding  in case of danger - underground. Maybe for all these years Grisha was thoroughly gathering information just to give a start for this operation. It's a shame we cannot ask him - he is very dead by now :(
