I have a feeling, that Celesta isn't adjusting well to the room-mate situation, as I can hear her whimpering and talking in her sleep.
A lot of things had happened recently for Casey, like finding out that she and Celesta were sisters, besides proving she was worthy of Pledge Day and Rocket had decided to help her and Celesta bond, by letting them share Casey's bedroom so Casey was going over to her sister's bed.
"Celesta you okay, are you having bad dreams?" she asked softly, seeing her awake despite shaky and stunned that Casey was there, feeling bad that she had woken her up since she needed her sleep, to grow.
"It's alright and guess you're having trouble sleeping, after what happened?" Casey asked, seeing Celesta nodding, giving Casey an idea knowing night-lights would make her sister feel better to sleep through the night, surprising Celesta.
"It's alright, as I sometimes use an nightlight to help me sleep, and uncle Rockie and the others won't make fun of you." Casey told her, plugging it in, shinging through the darkness of the room, makimg Celesta feel better, lying down in her bed fallimg asleep.
That made Casey happy, getting back into her own bed, cuddling her stuffed Groot, Flora goijg back to sleep.
Later the next morning, Casey was up but let Celesta sleep in, seeing both Gamora and Nebula wondering why they were here, hearing Rocket say they were going to help her and aCelesta bond as sisters, asking where Celesta was, hearing her say that she was sleeping after having bad dreams.
"That's very sweet that you were helping her, including sharing your nightlight with her to sleep." he told her drinking coffee seeing her eating breakfast, to fuel up for her day seeing a sleepy, grumpy Celesta join yhem, making Nebula chuckle at this.
"Maybe breakfast will make you feel better, as Casey told us, you were having trouble sleeping." Rocket told her.
"Y-Yeah she's been nice to me, you know?" Celesta said not giving him eye contact, making Gamora and Nebula, especially Nebula understood how she was feeling wanting to talk to her alone, making both Gamora and Rocket exchange a look, letting her makimg Casey curious, about why Nebula wantedto talk to her sister, making them explain that Celesta and Nebula might become friends.
Nebula chuckled as she and Celesta were rough-housing chuckling, giving Nebula an idea, because there was pro-wrestling in the galaxy makimg Celesta impressed, wanting to see makijg her smirk getting into her ship, taking off, makimg Casey and Gamora worry, until Rocket showed her aNebulas's text makimg them relieved.
"Yeah, like when Casey sleeps with me, because of thunderstorms, or bad dreams." Rocket said to Gamora.
Later Celesta was back, with pro-wrestling merch including a stuffed doll of her favourite wrestler, making Casey and Rocketbhappy that Celesta was happy, and into pro-wrestling knowing they could use this, seeing her go to her and Casey's room.
