The real story of how her Alters became her alters, by the way, her mom's name is Hot And Sour Soup. HASS is a bitch of a mother, okay? She is a terrible mother. Anyways...
When ER was Three years old, HASS gave her a black eye and threw ER to the wall three times. Pacifier then appeared in the headspace and saw ER crying. She fronted and stopped ER from crying and just tried to find the nearest toy and play with it to calm ER down. She was successful!
When Egg Roll was 7 she was introduced to a game called Fortress Dawn (Fortnite in the AWQ universe) and at first she was skeptical of it but in the headspace, Trading Card appeared and fronted.
The day before Egg Roll's 13th birthday, RS appeared in the headspace only to warn her about puberty, but he realized he was stuck in the headspace as an alter.
When Egg Roll turned 15 years old, she wanted to fit in with the other girls but she knew she wasn't able to. But HB showed up and decided to glam ER up. So she fit in all because of HB.
When ER was 10 she wanted to learn how to skate, but couldn't get the hang of it. She tried 10 times and before she considered giving up, SG appeared and fronted to finally complete what ER couldn't!
When ER was 14, and trying to solve a hard equation on her test, she almost gave up on it, but then PB fronted to solve the hard equation. Even that was enough to have her get a good score on her test.
When ER was 15 years old, she was still being verbally and physically abused by her mom, which caused Button to not only appear in the headspace but to instantly front and fight back against ER's mom. They slapped her 5 times before eventually getting grabbed by the wrist and dragged to ER's room and getting locked in the room...
When ER was just 5 years old, she was still going through a lot of pain and trauma, mainly involving HASS. Recently she had developed a little hobby, drawing! She showed her mom the picture she drew of her and her mom. HASS ripped the drawing to shreds. ER was devastated. Daisy appeared in the headspace and fronted only to see that ER had made some beautiful pictures. She then said, "Wow! Did you draw these? They look so beautiful!"
When ER was 13 years old, and she was watching tv, she saw an ad for HiHeels Drag Race. She had a favorite character named, Marble. Marble's drag was colorful and expressive. Unfortunately Marble died at the age of 35. But He eventually ended up in the headspace. He fronted for a bit to see his supposed new appearance in the mirror. He was in the body of ER.
...Minutes pass by as ER cries in her room as she is still locked up in her bedroom. Ballet Shoe appears in the headspace and fronts without hesitation. She decided that enough was enough. She found her way out of her room using a bobby pin. ER also conveniently had a heavy trophy in her room, so BS grabbed that and yelled out for HASS. And charged at HASS and hit her in the head as hard as she possibly could. She then let ER be Co-Con, and she told ER to pack up everything she needed to run away.
As for HASS, she was knocked out for a couple hours, all her money was taken, her wallet was stolen, her food supply was stolen. And her head was cracked. She woke up to realize that she had lost the battle of mother and daughter... She then went on to find her daughter to end Egg Roll's life... Once and for all...
