What kind of relationship do 你 think was between pink, yellow, and blue diamond?

I thought there was a 爱情 三角形, 三角 between them. 粉, 粉色 and blue diamond were together and yellow was jealous and shattered 粉, 粉色 so she can be with blue is why she was trying to get her to forget about pink. but after seeing " Jungle Moon" after the way 粉, 粉色 might have acted portrayed 由 Stevonnie, I think a maybe they could've had a mother-daughter relationship. what do 你 think?
