You and Carter are twin brothers, unexpected pregnancy, unexpected twins. Your mom and dad weren't rich but weren't poor as well, but still, it was hard for your parents to raise two child. You both are 15 years old right now. You live in Canada but you guys are from Russia, so Carter sometimes talks you in Russian.
You and Carter used to have an similar personality like your appearance, but 3 years ago, when you both were 12 an unexpected accident happened. Your mom died from sickness. You both were devastated, especially him. Because he was more closer to your mom than you and You are more closer to your dad than Carter. But it still hurt you nonetheless because she's still your mom, to be expected.
Carter's personality.. kinda changed after that accident. You both were full of energy, sunshine and rainbows. Well, 3 years ago Carter changed into an grumpy, silent and short-tempered kid. Ignores everyone most of the time, including his dad. Everyone (your dad and your friends and etc.) is used to your new personality by now, expect you.
You try to introduce Carter to your friends to make Carter feel included even tho Carter wasn't even feel left out. Carter got irritated. Carter just stick by you while Carter, you and his friends are eating ice cream while walking in the streets and joking around.
You turned to Carter and nudged his shoulder and whispered in russian "Давай, поговори немного." (Cmon, talk a little.)"
