Ken looks down at his hands while he explains. He's not...sure what else to do. "Certainly, the people who forget you won't be sad you're gone. But they won't have happy memories with you, either. I don't want that."

To forget his brother......To forget Wormmon......Even though thinking of them sometimes hurts. Even though he's carrying this guilt over both of their deaths. If the cost of never knowing the feeling of having his Digivice struck from his hand was losing his recollection of blowing bubbles on the veranda....

Ken blinks, having just surprised himself. "That's right. I wouldn't want it. I wouldn't give up the good to erase the bad. I wouldn't want to forget you. Your kindness...."

Even if the person who made that call meant well. He looks at Madoka again. "I'd rather hurt and remember than be empty and forget."
