Alright, I said I was going to do this. Will be stopping and posting, and editing this. Since in doing it to music.
The way I see it, Pearl sees Garnet as a strong foot hold. Besides Garnet being a very close friend/ally/family, I think Pearl sees Garnet kinda of like a hold. Something she can hold onto for comfort or when she loses herself. Something she knows is real and, like I mentioned already, something she can hold onto.
Garnet, in return, accepts this. She tries to help Pearl and everyone else. Help with their problems, help them relax. Even if it doesn’t seem like it, she always has. Garnet tries to be a good role model whilst keeping things under check.
Mind you, Pearl is also the type to get easily flushed. She gets embarrassed easily and just blushes a lot. Doesn’t necessarily have anything to do with actually romantic feelings. Sure, Pearl might love Garnet as friend/family but they’ve known each other for a while.
Garnet is just strongest person to hold onto and usually knows what to do when no one else does. That’s why Pearl grabs her arm. She feels the most reassured and safest with Garnet. Now that Rose is gone anyways….
