Dipper P.O.V

I head back upstairs with Bill after we talk. I still have many more questions about this alternate universe. My mind is overflowing with questions.

'Why wouldn't I want to come back to Gravity Falls? Bill did terrify me, but even then I still wished to return. What would make me want to stay away? I love the mysteries that Gravity Falls still has to offer. And if I'm not with Bill in this universe, or any other, who do I end up with? I certainly don't want to spend my life alone.'

None of the decisions I've made in this universe make sense in my mind. It doesn't seem like the choices I would make. One would think that I would be able to predict the decisions another version of myself would make. This whole situation only gets more and more confusing.

Bill pulls me into bed and holds me close to him. I don't exactly notice because I am too focused on my thoughts. Bill begins to play with my hair.

"You can't always predict your own decisions, Pine Tree," he says with a soft laugh.

"Why not? You should be able to, technically speaking. You know yourself better than anyone in the universe," I argue.

"That doesn't mean you'll be able to interpret your move before it's taken. It depends on the universe you're in. Not every version of yourself has had the exact same experiences. There are infinite versions of you, Pine Tree. You can't be like all of them," he explains.

Now that Bill has explained it more thoroughly, it makes a bit more sense. I suppose that anything is possible.

'There could be a universe where Bill's Weirdmageddon is actually successful. I probably die in that one. There would be universes where I don't ever go to Gravity Falls; universes where I never leave Gravity Falls. The possibilities are endless.'

"I guess that makes sense."

Bill hums softly and continues to play with my hair. The more I think about it the more I wonder why Bill chose me. If there are infinite versions of myself, what makes me special?

"Bill," I say softly.

"Yes, Pine Tree?" he asks.

"If there are infinite versions of me, what makes me special to you?"

He looks almost surprised by my question. It's almost as if he never expected me to question it. That, or he never wanted me to.

"Well," he says after a moment, "you came back to Gravity Falls with the intention of finding me. You wanted to see if I was still alive. And you didn't run when you discovered I was still here. There's something different about you and I like it."

A smile slowly finds its way onto my face. Bill really is sweet when he tries.

"I'm glad you picked me," I tell him, kissing him gently.

He smiles and kisses me back. I truly am glad that Bill picked me out of infinite other versions of myself. He makes me happy.
