Ok this is just me rambling about this, but look:

1. When Stevonnie is dreaming about Pink’s past, Pink’s and Connie’s memories get mashed up. And who is taken as Stevonnie’s mom? Yellow gets mashed up with Connie’s mother:

2. This is weak but… come on, Connie’s parents look so similar to Blue and Yellow. Priyanka has a temper that reminds me of Yellow’s strict one… and has Blue’s kinda similar hair style. Doug is more relaxed and less strict with Connie (it reminds me more of Blue…) and has a very similar hairstyle to what could be a human Yellow:

3. Steven saying they are family:

4. Cookie cat’s song says “He left his family behind”. We can all agree Cookie Cat is intended to be foreshadowing for Steven himself. Cookie cat even has diamonds in his little bag:

5. Come on, all these look like two parents scolding their child because she asked for expensive scuba diving lessons + equipment and decided she didn’t like water once on their boat in Acapulco:

6. Maybe this is a hint to what happened with Blue, Yellow and Pink, and what Priyanka understood with Connie when she saw she was now more independent. The similarities are… a lot, I would say:

Connie: “It all started as a tiny secret […]”

Priyanka: “Is that how you feel? Are we too controlling?”

7. Not really point seven but, look:

So… yeah.
