Look at the moment Steven sees Lars’ scar(on his eye) Steven’s a smart boy, he know what happened. Unlike us, he saw it all. He knows that the robot exploded, he knows what happens when robots explode. He sees Lars’ scar, he knows that the shrapnel went through his eye, past his brain. He knows his friend who about a week ago was baking some Filipino cake thing for a potluck, died. Hes a child, who knows that it’s his fault. Steven didn’t mean to but it’s true that he gave a list to peridot, it’s true that he didn’t force Lars to go home when he had the chance. Steven just brought that kid back to life. This is fucked up.
