Gwen and Erica

This explains the relationships between Gwen Orrcut and Erica Askiname.
==Original Universe==
Gwen met Erica Mader when she moved to Autumn Springs back in 2014. Gwen noticed she was sitting alone, probably because she was new and told Louis to invite her to sit with them. She defended Erica when Marmalade let out her anger on her for stealing her seat, and then the two started to bond. Gwen liked Erica, she thought she was a very honest and down-to-earth person with nothing to hide.....  it was boring, and very cheesy to her, something must have been up.
Months later, Erica Mader revealed herself to the gang as the incredibly wealthy Erica Askiname. Gwen knew her fake life was too boring. Erica felt bad for Gwen's horrendous look, and offered her to have plastic surgery on her to look beautiful, but Gwen declined, saying she's fine with how she looks. Gwen really didn't like how snobbishly rich she was, especially because she was dirt poor at the time.
Erica on the other hand, felt like she really didn't connect with Gwen as much as she did with the other two girls in the group, so she grabbed dinner with her at Applebees. Erica told Gwen that she had social problems, and Gwen went on to say that nobody's had it worse than she did, and that was the general mood of the dinner. Erica asked if she could see what her house look like, only problem was that Gwen didn't own an actual house.
The two then walked along the street and came across her home, a Dunkin Donuts. Erica looked absolutely mortified, so she ran away in disgust. All of the feelings of empathy Gwen had for that evening faded away, and Gwen hated her for that.
The next day Erica pondered in her mansion asking herself what to do about Gwen's "financial crisis", and then she had a brilliant idea. At 3AM, a mysterious figure went to Gwen's room at the Dunkin Donuts. She told the manager her name was Kathryn Orrcut, Gwen's sister. The makeup on her made her appear to be around twenty, so she let her go upstairs. Gwen asked what she wanted, and Erica took off her wig. Gwen slammed the door only for Erica to bust it back open. She told her to pack her bags, for tonight she would be staying with her, in her mansion. 
This completely shocked Gwen, she couldn't believe she was letting her friend stay at her luxurious high class raining money mansion. Erica had to check up on her because she was so surprised she couldn't move. Erica then picked her up and then the two left the Dunkin Donuts, where Erica's chauffeur was waiting in a white Lamborghini. The two bonded on the way to her Newington mansion. Gwen refers to Erica as her "savior" at some points.
Years later, as a birthday present, Erica convinced her parents to give Gwen a home of her own. Gwen almost cried, saying that she has never been so grateful in her life. She lived in that home until she got married, and when she did, she told Erica that she was going to move in with Ryan. Erica later sold the house and gave all the profit to the newly wed couple towards their mortgage and finances.
