Like my AU's "Potionate" and "Potion Triangulated," this is another way things could have gone wrong at the diner on the day of the Woodstick festival. All characters belong to Alex Hirsch, not me.
Potion Explosion
As soon as his fry order was put in front of him, (with the special pink "sauce" added by Mabel), Robbie picked up the basket and went over to the cash register.
"Hey, I ordered these to go!" he called to the back. "Gimme a box or something."
"I'm leaving," said Tambry, getting up from her seat and continuing her status update on her phone.
"Wait, Robbie!" Mabel yelled, running out from behind the counter. "Please share the fries with Tambry, just a nibble. I promise they will make you feel a lot better."
"Mabel, this blind date you rigged up for me is a bust," said Robbie. "I should have known not to trust a Pine."
"Sorry Mabel, it's just not going to work," said Tambry. "Robbie and I are so not happening."
Giving up on getting any service, Robbie threw a couple of dollars on the counter and headed for the door, still carrying the fries in the basket.
Dipper rushed in. "Mabel, Soos told me I might find you here. It's time to get ready to go the the Woodstick concert."
Mabel looked down at the floor, discouraged by the failure of her matchmaking attempt. Even with the help of a potion from a Love God.
"Out of my way, dweeb," said Robbie. "I've had enough of your family for the day."
As Robbie went past Dipper, he bumped into him, most likely on purpose.
"Hey, you got some of that sauce on me, man!" said Dipper.
"So? What are you doing to do about it?" Robbie said. He put one of the fries in his mouth and chewed on it while he stared at Dipper.
Dipper stared back, looking at him with new eyes. "I... umm... I'd like to invite you to go to the concert with me?"
"You know, I'd like that," said Robbie, with a new look in his eyes as well. "Your whole thing suddenly got a lot more likeable."
Mabel looked on in horror. "What have I done?"
