Siena

Siena is a minor antagonist in a few episodes of Fraternal Twins. She appeared in Totally Grounded alongside Allison, and First Day Back by herself.

She is “portrayed” by Lizzy Greene.

Personality
Siena is not the nicest. Along with her best friend, Allison, she despises Katie saying she’s “uncool” and “an embarrassment to hair accessories”. She and Allison also idolize Lindsay at first, saying she’s super pretty and looks like she’s very popular. This stops when Lindsay sticks up for her sister.

Totally Grounded
In this episode, Siena and Allison use Katie to get close to her sister and hang out with her. They end up dumping both when Lindsay stands up for Katie, and they deam her “not worth their time after all.”

First Day Back
In this episode, Siena is back at school with Katie, she keeps bugging her, and she asks her mom for help.

Allison
Allison is Siena’s best friend, they like a lot of the same things, and they are both the mean girls of their school. Allison is only seen once, so that’s the only time she and Siena are seen together, and they seem to like being the mean girls together. They have a lot of things in common with each other,

Katie Davenport
Katie is a girl who is in the same middle school as Siena, they don’t like each other very much since Siena and her friend,  Allison, are both mean girls. When they are first seen together, Siena didn’t want to hang out with Katie, thinking she was weird, and in  First Day Back, they are both now in middle school together.

Trivia

 * She goes to Jendenville Middle School.
 * She is a year older than Katie because Katie said that she went to her school before, and they go to the same school starting in First Day Back.
