"You need to quit this game right now or else..."

"The reason why I want you to quit is because this game is unfinished. Please quit the game, if you stay I won't be happy..."

"QUIT. THE. GAME."

"Okay, fine, you got me..."

"It appears we never had a proper introduction before..."

"I don't really have a name per se, but you can just call me Assist. What's your name?"

"[your name], huh? Pretty stupid name if you ask me. Not being mean though."

"First of all, sorry for scaring you earlier."

"It's just that I have huge anger issues. And when I get angry, I get scary at the same time."

"Second, yes, I'm the creator of the unfinished game."

"And because I'm still mad about what you did, I will make you watch me finish the game."

"Remember, do NOT make me mad. You will not like it when I'm mad."
