Johns POV

"DAD! What are you doing here?!" I hug my dad. I hadn't seen him since the whole Betty Crocker strife when I moved out! "I just missed you so much and I need to tell you something." "Dave why are you with him?" "Oh he was lost looking for you so I let him follow me. I thought I'd surprise you and stand behind him." "Oh cool. Come on in guys!" "Y/N, Terezi! Come meet my dad!" The girls walk out of the living room to the front door. "Y-y/N?!" My dad stutters her name. "Uh.. hi?"  She seems Elly confused. "I-I... John that's what I wanted to talk to you about... You have...a sister..." "Oh cool who!?" "Oh, uh Y/N is your half sister." (Half? Yeah half!) My and y/n eyes both widen.
"Fu¢K that's awkward." Terezi commented. All except dad knew I was flushed for y/n.

Y/N Pov

Well I guess I just just spill the news right now. "Uh actually I needed to talk to all of you so I guess now's a good time." I begin to fidget with my fingers. "What's up y/n?" Dave smiled at me. "Mituna got me... Pregnant." I blush and tear up. Every one's faces lit with joy. "CONGRATULATIONS Y/N!" John hugged me tightly. He always knew how to cheer me up.
