"I don't want to go back anymore, I'll just stay here with you!"

Billy and Grim were sitting on a log next to what tried to look like a campfire, most likely set up by Billy. Grim visited him early that day, mainly to bother him about his own problems than to listen to his stories or to accept any of his freshly made presents for Mandy.
Not that Billy minded it that much, he was already happy with Grim coming to visit him.

"But didn't you say you was busy watching House on TV?" he asked.

"It's terrible!" Grim cried, "I don't know what that girl is up to, but I just feel the stress rising everytime I enter dat house. You can't have any normal conversation with dat girl, she's far from social! Yesterday I went upstairs to offer her some selfmade pudding, and she told me to suck it!"

"I'd like to suck your pudding, did you bring me pudding?"

"Billy, I'm trying to open up to you!" Grim yelled, "She's up to no good, and I tried to ignore it..but well..it's getting lonely.. and I just want someone to judge me cooking skills."

"Maybe she's crying in her room because she misses me so much."

Grim didn't even bother to answer that, it was an incredibly stupid comment. He gave Billy a dirty look and resumed his yammering.
He went on till late in the night, and even though Billy really wanted to have a turn, he let him finish. While Grim's story made Mandy the obvious "bad guy", apparently it didn't occur to Billy since he asked him the very second he paused:
"But Mandy misses me, right?"

Grim looked at him with big eyes. That's it. He thought it was time this boy knew the truth. But how was he able to put Mandy's evil into words that even Billy understood?
..And why should he even bother to "protect" him from the blonde menace? Well, he's dumb, but he's not a bad person. Mandy doesn't deserve a friend like him. And Mandy doesn't deserve a friend like Grim!

Grim cleared his throat, and slowly said:
"Billy, Mandy is a witch."

"SHE CAN DO MAGIC TRICKS? CAN YOU ASK HER IF SHE CAN PULL A HAT OUT OF A HAT?"

"No, Billy.." Grim said, "She's like..dark seed."

"If we bury her, does she become a dark tree?"

"NO BILLY, Mandy is bad, dangerous, heartless, a person you should avoid, not befriend! Do you understand, Billy?"

Billy scratched his head, and a confused frown appeared on his face. Then he said:
"Grim..I don't understand why you's suddenly telling me this. You were telling me about your swell vacation 5 seconds ago for 1728000 seconds long."

Grim started to lose it.
"Don't you see I've been lying to you for almost 2 months now?"

"You didn't has a swell vacation?"

"Billy, listen man, I've been telling you all day how terrible Mandy's been to me and how she never left her room ever since vacation started! Dat is NOT a swell vacation. And she didn't want any of your gifts, she didn't want to hear any of your stupid stories, she doesn't miss you!"

"But Mandy misses me, right?"

Grim was clearly losing his patience. Mandy wasn't good company, but Billy wasn't any better to hang out with as was just proven. It disturbed him how nobody was ever willing to listen to him, or was just too stupid to have a normal conversation with.
He was tired of being afraid and angry all the time.

"Listen..it's late, it's time for me to go back home."

"Did I say something wrong? I thought you wanteded to stay here with me."

"No, Billy. Your intelligence is testing my patience."

Grim stood up, summoned his scythe, and opened a portal back to Endsville.

"Grim, wait." Billy suddenly said.

Grim turned around.
"What is it?"

"I know you lied."

"You do?" Grim said surprised.

"Yeah." Billy replied.

"You're not messing with me, are you?" he asked uncertainly.

"No.."

Grim closed the portal and sat back down on the log next to him. This might be another one of those moments were Billy ment something completely different, but he was ready to take another chance with the idiot.
Though he wondered who was the real idiot in this picture. Maybe he should stop believing the the boy so much, he's pretty much a hopeless case.

"So." Grim began, "We're not talking about my vacation now, are we?"

"No, Mandy."

On the other hand, Grim thought.
He dismissed his scythe, and put his hands on his lap.

"Well..?" he said.

Billy's eyes moved from Grim to the ground.
"I know Mandy couldn't have liked any of my stuff, like you say. But I just wanteded to believe that she did..like you said."

This was rather a painful moment.
Was it selfish of Grim to destroy the image of a person someone liked? It was. But on the other hand Billy claimed he already knew she didn't appreciate any of his gifts.
He sighed, but didn't say a word, and waited for Billy to say something again.

Billy's eyes moved away from the ground, back to Grim again. They stared at each other for a little while, and then Billy said:
"Can you ask her to be careful..?"

To be careful? Does Billy know more about Mandy's plans than anybody else? Grim wanted to ask him, but he already walked away and had entered a crappy version of a tent.
It was no use to chase him; most likely he didn't want to talk about it anymore, anyway. But this could be used against Mandy, Grim thought.

He stood up and teleported back to Endsville. Whatever Mandy was doing right now, it had to wait, he wanted some clarification. Right now.
"..And I so promised meself to ignore dis mess.." Grim said to himself, as he walked towards her front door. "I guess it's not in a best friend's nature."
