Molly's POV: I was walking to the mystery shack, Bill by my side. For whatever reason, he had become more protective of me ever since the singing incident.
As I walked into the shack, I noticed a girl leaning up against the counter. She had grey hair, long pigtails, and her eyes were a strange shade of light blue. On top of that, she wore a skull clip in her hair, a black dress shirt, and a white skirt, adorned with grey bows around the edges.
I was confused, I'd never seen her in Gravity Falls, but figured I'd might as well introduce myself.
"Hi! I haven't seen you in Gravity Falls before! Are you new?" She was taken by surprise and there was a moment of silence before she answered. "Oh, uh, hi! I'm Evangeline, and no, I'm not new here." "Well nice to meet you Evangeline! I'm Molly!" I smiled and shook her hand, which was, surprisingly, cold.
"Oh!" I chuckled,"Excuse my manners, this is Bill, Bill Cipher! Bill," Bill seemed to be snapped out of a daze and he looked at me, "this is Evangeline." Bill waved and then continued in his silent daze.
"So, I'm assuming you know Wendy?" Evangeline nodded, "Yeah, we're sisters." "Oh! Well, I'm glad I met you Evangeline!" "I'm glad I met you too, Molly! Now, please excuse me, I've gotta go, bye!" "Bye!" I waved as she walked away.
"You never mentioned that you have a sister!" I said to Wendy, excited. "Wait, how'd you know that?" "She was just here silly!" Wendy looked confused. "What? She couldn't have been." "Wha-why not?" Wendy looked at me solemnly. "Because she's been dead for years."
