Background: Tessa and Tasha are twin sisters, Tessa being the older twin by five minutes. Their mother died in childbirth, and their father died later on in a shooting. The two then had to live with their aunt, which was hard for Tasha because she was born with the inability to walk. A year after the twins moved in with their aunt, they were visited by a demon named Claudius, who offered to give Tasha the ability to walk in exchange for using the twins' bodies once to observe and learn how humans were/are. Tessa was a bit sceptical about the offer at first, knowing that demons often tricked humans into getting what they wanted. She had studied the paranormal and supernatural since she was 4, so Tessa knew just about everything there was to know about demons. Claudius, however, convinced Tessa otherwise by saying that he was only studying humans to find ways to benefit them, and that he wasn't like the other cold-hearted demons Tessa had read about. He then also offered to make the twins look younger than they were in the future, as they both wanted to be out of fear of being rejected and shunned by people.

After agreeing to the deal, Tasha gained the ability to walk, which was a miracle to many people, and as promised, they let Claudius one time each to find ways to benefit humanity. He kept his word on that, causing many women and men, young and old, to live longer than they were supposed to. After their aunt died, both of the Hallwell twins were already in college, and were in their older teens. Tessa got a very good education, getting many diplomas in many different courses. She has many Ph.Ds as well, making Tessa one of the smartest people that had been from Gravity Falls. Tasha hardly graduated college, having a learning disability. No matter how much tutoring and help she got, Tasha always had a hard time learning, and still does. Tasha especially has trouble in Algebra, as well as Science. Ironically, Tessa is very well educated in these subjects.

Tessa and Tasha return to Gravity Falls when they are in their late fifties, though they look like they're in their thirties. Upon returning to their hometown, Tasha goes out to town, seeing that everything looked about the same as her and Tessa left it. Tasha then meets Dipper and Mabel, two sixteen year old siblings, in town, who she immediately becomes friends with. Tasha meets the two again, along with their gruncle Ford, who had mistaken Tessa for her. Since Tessa and Tasha are identical twins, it was hard for anyone to tell then apart. However, there were three ways to tell the two apart. One way was that Tasha usually wore contacts, while Tessa usually wears glasses. Another one is that they have different clothing tastes. While Tessa likes casual clothes and formal clothes, Tasha likes bright colored clothing and loose clothing. The last way to tell them apart is their eye colors. While Tessa's eyes are dark green, Tasha has dark green eyes with a light blue tinge. You can only tell this if you get close enough to their face, which is rarely allowed by the two.

Tasha and Tessa live close to the Mystery Shack in their childhood cabin, which allows them to easily visit the Pines. They love to visit them every day, as they are very good friends with them. Tessa also has a secret crush on Ford, and Tasha has one on Stan. They both think that they don't feel the same because they look younger than the two, which would cause people to judge them. They don't want to cause judgement to the two, so they keep quiet about their crushes. Dipper and Mabel have recently found out the Hallwell twins' secret from Violesta, since she can read their minds, and they're both trying to help them out secretly. It's a bit tricky with Gruncle Stan and Tasha, but the plan involving Ford and Tessa are going well.

(I'll probably update their backgrounds and profile later, so stay tuned. I hope you like the characters, and until the next update, BYE!! ^^)

P.S. The twins' favorite song has recently become Feelings by Maroon 5, which is the video above.
