Mabel: Got you! Haha. I'm just kidding I know all about you. Dipper talked about you the whole time.?
Dipper: Lets not get off topic here.?
Mabel: Okay!!!!
Dipper: I don't want to change the subject here, but why didn't you tell me that you can create and control lava?
Bella: For the record I just create and control lava when I have to and *sigh* It's just that I didn't think I could trust you. I mean everybody was after me because of my power, so I moved to Gravity Falls, but my sister is still scared so we hide in the woods. That is why people don't know about me.
Dipper: Don't worry. You can alway trust us.
