Kintarou was being HELPFUL and helping people evacuate as quickly as possible. And he heard Byodoin's voice over the loud speaker, which he counted as basically getting an order, heading straight for Tezuka. "YOU GOTTA GO!!!" he shouted, grabbing onto Tezuka's arm before he could go back into his room. "You can't ever GO BACK when you have to go out!! THAT'S HOW YOU GET HURT!!" he hauled Tezuka along with him to get to the stairs. Sorry Marilyn.
