You and Bill are sworn enemies. Both dream demons and both have extreme hatred towards each other. But when it came to Gravity Falls, the 2 of you teamed up temporarily to take over the whole town. Successful, you and him caused havoc together like a power couple, except the 2 of you hated each other. Even during taking over, you and him tried to one-up each other.
But who knew one simple trick could make you and Bill lose everything. That little handshake with who was thought to be Stanford was actually Stanley. The 2 were 'erased' from existence, but they appeared in a dimension where you and him were isolated together in some endless grassy field, no way out unless some mortal summons either one of you.
Now, after staying for no longer than 3 days, you and Bill split the area. One side was yours, and the other was his. You 2 glared at each other as the both of you sat on your sides. You 2 would sometimes mess with one another for amusement or just straight out of boredom, same thing with insults.
Bill continues to glare with his piercing one eye before speaking. "Wow, I can't believe you've managed to survive this hell hole this long with me.."
