"Bill why is it the every time I come over to your place you act like your hiding something!?" Dipper asked arms crosses glaring at her boyfriend.

"I'm sorry Pinetree but I don't know if I can tell you." Bill admitted head down in shame "I'm sorry Pinetree." He said.

"No." Dipper said sighing "Until you can learn to trust me you and me don't exist!" She said breaking up with him points at the door.

"But Pinetr-" Bill was cut off by Dipper.

"No!" Dipper snapped eyes watering "You no longer have the privilege of calling me that! Her out!" She yelled running hip the stairs.

"Okay." Bill muttered walking outside to be alone for awhile "What am I gonna do?" He said to himself.

"Maybe you should tell her the truth Bill."  Will said teleporting next to his older brother.

"What if she doesn't approve of me being a demon?" Bill asked.

"Bill love can conquer anything and Dipper loves you already and beings demon isn't gonna stop her from loving you." Will said smiling sadly.

"Your right... At least I hope your right." Bill said smiling sadly too then starts to sing.

~I've waited for this long
To talk about what's been going on
Afraid of what might change
If I reveal myself to you
Cause there's another side to me
Something that you have yet to see
What would you say? What would you do?
Where would you go if I tell it to you?
Should I share with you my biggest secret?
Biggest secret
Should I share with you my biggest secret?
Biggest secret, part of me
There are loves
That you have for life
And I don't wanna feel like
I have to tell you lies
And I would be there
For you no matter what
And I know you feel the same
And who I am won't need to change
And I can be
Whoever I need to be
So I share with you my biggest secret
Biggest secret (Part of me)
I share with you my biggest secret
Biggest secret
So I share with you my biggest secret
Biggest secret (Part of me)
I share with you my biggest secret
Biggest secret, part
Of me
