Mabel:

This was officially too much information for me to handle right now. On top of everything that we'd found out today, an old guy that looks like Stan comes out of the portal, picks up one of the journals with a six fingered hand, that's right, he had six fingers! Then Stan says that it's the author of the journals that Dipper's been obsessed with all summer, and that they're brothers!

I could see anger clouding Dipper's face before, probably at both me and Stan, but hopefully he'd ignore that for the moment and start fangirling over the author. Unfortunately, the author attacked Stan before he could get the chance.

With my usual overly-positive attitude slightly faltering, I approached the two fighting old men and said, "Hey, hi. Mabel here. Quick question... What the heck is going on here?!"

Dipper:

"Stan, you didn't tell me there were children down here," the author said, like that was the surprising part.

"They're your family, Poindexter, Shermy's grandkids." Well that was a let down. For a minute there I was sure that the author was actually my grandfather. Mabel and I have never known our grandparents from Dad's side. Mom's parents, Gramps and Gram, lived too far away for us to go there this summer, which is why we ended up with Stan. I guess Dad's dad could still be around, but I've never heard of him. I didn't even know who Stan was until the beginning of this summer. And I realized that I still don't know him, and that he had some explaining to do.

The author walked up to Mabel and shook her hand, and she took note of his six fingers. I'm not going to even get in to the whole four vs five finger thing, we've always just ignored it.  The point is, the author was the only person I've ever heard of who had six.

Well anyway, I was still in a state of shock. "I-I can't believe it! Your the author of the journals!" I shouted, as it was just now sinking in.

"You read my journals?" He asked, pulling the first one out of his coat.

"I haven't just read them, I've lived them!" I exclaimed. "I've been waiting so long to meet you, I don't know what to say, I have so many questions!"

Then, of course, I started hyperventilating. Way to make a first impression. At least I didn't throw up, although I was pretty close.
