"Sorry dudes." Soos said wiping the slaves into pulling the rock more.

"If your sorry then why are you doing it?" Ford asked.

"My cousin normally does this but since he kicked the bucket it's my job now." Soos explained then whipped them again.

"Have you ever considered having someone else do it?" Dipper asked winking at her grunkles and sister.

"Your right! I'll ask right now!" Soos said walking away unknowingly leaving the slaves unsupervised.

"Kid your a genius!" Stan said rubbing Dipper's head affectionately. The grunkles and sisters both make a break for it.

"HALT!" A deep voice yelled making the four stop in their tracks frozen knowing who yelled the order their pharaoh Bill Cipher a dream demon who can kill anyone with a snap of his fingers "Well well well what do we have here?" He asked taunting them.

"The pines family sir! Stanford and Stanley pines and their great nieces Mabel and Mason aka Dipper!" A guard answered.

"I was wasn't talking to you." Bill said coldly making the guard bow his head in forgiveness.

"Sir please don't hurt my nieces I'm begging you!" Stan begged on his knees. Bill looks at the sisters up and down smiling.

"You!" Bill snapped at Dipper making her gulp at him "I'll let your family live in the pyramid if you become my personal slave." He offered hand out in blue flames meaning business "Deal?" He asked smirking.

"Why would I do that?" Dipper questioned glaring at Bill making him chuckle and take her face in his non flamed hand.

"Hey I'm being generous either accept it or execution your choice." Bill said.

"Fine I'll be your personal slave in the terms you keep my family alive and happy." Dipper said face stoic taking Bill's flamed hand.

"Deal!" Bill and Dipper said with Bill shaking Dipper's hand sealing the deal. Suddenly Bill tugs Dippers arm to his body causing her to blush being to so close to muscular tanned chest and with Bill sniffing her hair.

"Wait what?" Ford asked out of nowhere looking around confused.

"Oh Dipper..." Mabel whispered head down and at that time Soos appeared.

"Oh man am I fired?" Soos asked. Bill out of nowhere kisses Dipper and takes her bridal style in his pyramid with guards and family in tow "So no?" He based rubbing his neck confused.
