The unsolved mysteries of Gravity falls

The begining

The sun was burning Mary's face.Her green eyes were sparkling like two emeralds in the light.Her ginger hair was tangled like she was wearing an afro wig.She woke up and quickly ran tot the calendar.
"YES!yes!yes!Yes!Summer,here I come!This is going to be the best summer!Can't wait to meet David!ILLY!STACY!YEAH!"she said screaming and dancing.
She fast changed,brushed her hair and her teeth and ran outside!
Mary stopped running only when she arrived at a pink and yellow house that was floating.She jumped to reach the stairs and knoked at the door.
"ILLY...COME OUT!"
The door opened itself...Illy was sitting next to the door being sleepy.
"Just a second,Mary!"she said closing the door.In a second she opened again..this time she was dressed and ready to go.
Both jumped back at the ground and started to walk fast.
"We have to go to David's house,then at Peter's...we have to go in the bus station to wait Finnic and Stacy to come...said Illy counting all they had to do.
"Oh...I can't wait to finally meet her..again...I haven't seen her in like an year."said Mary full of entusiasm.
"Yeah...cant wait to hear all their stories from Antartica"
They arrived at a big and beautiful house with a huge garden.
David was already outside watering the plants.
"DAVID!David..."said Mary running to him."David!I missed you so much" she said hugging him while Illy was looking at them like a paint from a museum.
David kissed her on the forehead and hold her.
"Can we go now...we need to go get Peter to wait for Stacy"said Illy blushing a bit.
David and Mary were holding hands.
Illy was walking while smiling.
After 5 minutes of walking..we saw Peter texting while sitting on a bench..Illy was trying to hold her entusiasm and just said "Peter!We need to go  wait Stacy and Finnic."
