My own Gravity Falls like thing?

Feelings/Rose's hair

" B-Bill I-I " Kat said as she took a deep breathe so she could speak clearly  " Bill I forgive you, a-and I l-love you t-too,heh I guess that's why I was upset " Kat said laughing a bit trying not to seem weak when Bill heard her say she loved him back he hugged and kissed her on the cheek making Kat turn a bright red as he pulled away from her and she started to speak again " so...why did you get mad in the first place ?" " Well....I was jealous, you looked so happy to meet someone else and my cousin out of all people, I couldn't help it " Bill said looking at the ground looking slightly  guilty for what he had done as Kat smiled " Dude I don't even think I could get attached to someone else I've got you " Kat said as she lightly punched him on the arm to act like her normal tomboy self making Bill laugh at her actions as he grabbed her hand and the two walked back to the cabin " so what did you think of Will " Bill asked " well He's nice so I think we will be good friends " she said while smiling as the two finally arrived back at the cabin and when they walked in they saw Dustin holding back a VERY mad looking Rose I mean she looked as if she was about to kill someone but for some reason her hair was red a VERY dark red like blood which made Kat think ' if her hair is red then does that mean her hair changes for her emotion 'cause that could be an effect of being an angel although any other time her hair is pink now that I mention it her hair did look a darker pink when Bill said that to me ....' she was rambling on and on in her thoughts until a hand waved in front of her face as Bill said something " earth to Kat " and he slightly knocked on her head and spoke again " hello???? anybody home ? " he said trying to surpass a laugh when Kat came out of her thoughts with a derpy looking face and when Rose saw this she started to laugh like crazy and her hair turned back into its pink color so her hair does change with emotion........
