Dimitri: Mom? Who is that?
Sandra: Well Dimitri, this is Peni and she's going to be living with us. So she's your new sister.
Dimitri was seen looking shocked at what his mom had said.
Dimitri: Sister?
Sandra: Yes, your sister. So She'll be staying in your room until her room is ready.
He watched Peni walking to his room as Dimitri went there to see Peni was placing red tape across the floor in a line.
Dimitri: What are you doing?
Peni: Well I have my side and you have your side.
Dimitri looked at Peni in annoyance as he then dropped the lamp as it opened up and purple smoke came out we see a girl with purple hair in a red dance outfit was seen in the room as Dimitri and Peni looked at her in shock.
Dimitri: Who are you?
Shantae: My Name's Shantae, half-genie hero.
Dimitri: Ok.
Shantae: Where am I? The last thing I remember was being stuck in that lamp in Pariah's castle.
Dimitri: Long story short, I may have found you and brought you here.
Shantae: Oh well thank you.
Dimitri: You're welcome.
Dimitri then laid down on his bed and he went to sleep knowing tomorrow will be a big day for him as we see the morning come as Dimitri was dressed and was heading out the door.
Dimitri: Hey Mom, I'm gonna see my friends.
Sandra: If you're going out, you better take Peni with you.
Dimitri: What?! But mom!
Sandra: No buts, I want you and Peni to get along as siblings.
Dimitri: Fine.
We later see Dimitri walking through town as Peni was walking with him as we see him arriving at a smoothie stand as he sees the group was there as they saw him.
Ashton: Hey Dimitri. (Sees Peni) Who is that, dude?
Dimitri: (Sighs) Guys, this is Peni, my... sister.
Alex: Sister?
Ashton: Since when did you have a sister?
Dimitri: Since yesterday. Mom's having me spend the day with Peni.
Daphne: I think having a sister will be good.
Dimitri: Easy for you to say, you have many sisters.
