Maybe Mabel isn't running away from something. Maybe she's running too someone....

It’s definitely a possibility. Anything can happen in the next episode. (By the way, buckle up guys, and prepare yourselves for some theorizing, haha.)

Though what I’m gathering from the trailers that we’ve seen, I can see her getting upset over what occurs in the next episode. The episode description does say:

“Mabel decides to plan for her and Dipper’s 13th birthday party. Meanwhile, Dipper ventures below the town to find its most shocking secret.”

Obviously from what we’ve seen is that Dipper and Mabel’s 13th birthday is coming up, and Mabel is very excited. And may I mention that from what we saw in Blendin’s Game, Dipper and Mabel have spent every birthday together.

“We’ve shared every birthday together, so we know how to make them perfect.”

I’m also assuming that they may have planned some things together for some of their birthdays in the past as well?

Anyways, with that in mind, as well as their 13th birthday coming up, Mabel’s stoked and ready for their birthday to come up, and brings it to Dipper’s attention. She’s already ready to start planning for their special day, and I can see Dipper being all up for it as well.

But obviously something will go wrong around town. Something big, and we see Ford in the teaser/trailer announcing it, and confronting Dipper about it. We obviously see Dipper being with Ford revealing some shocking secrets of the town, though did you happen to notice this? And what Mabel says?



“It’s okay, Dipper. You should totally go with Grunkle Ford to save the world, or whatever.”



I could see Dipper agreeing to help Mabel with party planning, but once Ford brings the issue up and tells Dipper he’s the only one who could help him, Dipper probably doesn’t know what to do. And based on what I just mentioned above, Mabel is telling him to go ahead and go, and that she can do the planning on her own. And Dipper goes, and leaves Mabel to handle the planning on her own.

Though throughout the day, we see Mabel probably trying to plan for their party, but from the looks of it, things don’t go quite as planned.

Perhaps maybe her friends are busy? She’s saying goodbye to them? Who knows. But obviously whatever went on, it’s starting to make Mabel feel a little upset. Things don’t exactly go her way, and it could lead to her sitting somewhere alone as we see below.

From the recent trailer, it seems like she’s trying to contact Dipper here, though he can’t stay in contact with her for long due to things happening below the town with Ford. And I think by then she’s realizing more that ever since Ford came through the portal, Dipper has been spending a lot of time with him, and/or maybe that she’s realizing that their summer is ending, and that means they’ll have to leave Gravity Falls. Eventually Mabel heads back to the shack, and is still upset over what has happened throughout the day. Dipper is still out with Ford, and it looks to me her friends aren’t around to comfort her now.

Though, I’m assuming once Mabel is back at the shack, Stan notices her looking down and comes up to the attic to try and comfort her. :’)



But once Stan leaves, I can see Mabel reflecting over what’s been happening (maybe over what’s happened during the day, and the whole summer too, since she does have her scrapbook out). She waits for Dipper to come back, and when he eventually does, it looks like he comes back pretty late.

The two start conversing, and I’m going to assume it’s over Mabel realizing that summer is almost over for them, and/or mentioning that Dipper left her behind all day to go with Ford. And due to Mabel bringing that up, Dipper may bring up that she was the one that told him that it was okay for him to go with Ford. And this will probably lead to what we see below from the SDCC trailer. An argument between the two.

And in the end, I can see it leading to Mabel getting so upset, that she leaves the shack by herself (either out of sadness, anger, or fear? Maybe a combination of all three? I’m not sure.)

But if this turns out to be true, this most certainly cannot turn out good. Maybe she thinks of a way to try and fix things? Maybe she runs into someone? Or is approached by something?

She’s outside the shack (no longer protected both mentally and physically), alone and vulnerable, and to a certain someone, this may be the perfect time to strike. Or she could come across anybody, really. Who knows.

AND THIS IS ALL JUST ASSUMPTIONS. I could be completely wrong, and to be honest I don’t think I really pulled this all together very well, but I was just writing out what I was thinking, hahah. All I’m trying to get out is that something’s most likely going to happen to Mabel by the end of the episode, and from what we’ve been seeing from the trailers, it certainly can’t be good.
