Do you believe Maya turned into Riley if so since when?
(Very late response to this past hot topic, but since this was in my drafts, I thought that I might as well post it. Additionally, please do not think I mean to bash any of the anti-Rucas ships - this is all just my opinion of what actually happened.)
So I don’t think Maya “became” Riley per se, but I think she did take on her perspective. If you watched Girl Meets Yearbook (where she becomes Riley after Riley becomes goth and Farkle becomes Donny Barnes), you would see that Maya realized that everyone needs a Riley, no matter who plays her. That + Maya saying that Riley sees Lucas as a brother led her to go on this journey to see if Lucas was really right for Riley, which I actually believe - that if she really did become Riley, it was to protect her.
But the thing is, like Katy said, when you’re too close to someone, when you care too much about them, you won’t be able to see correctly. This happened with Maya. She misunderstood Riley’s feelings like this, believing that Riley’s feelings for Lucas were platonic. Additionally, she had a subtle belief that the class was right - that she (Maya) and Lucas were fire together. This led her to try it out with Lucas in GMTexas, since she had believed Riley did not like him romantically. Riley backed off, hiding her true feelings because she would rather hurt herself than her best friend.
At the time of GMTexas, I was angry because I thought Maya didn’t realize she was hurting her best friend. But after Girl Meets Ski Lodge part 2, I realized that Maya just thought she was protecting Riley, not understanding that she didn’t really need protection from Lucas after all. So the main lesson here is about Riley and Maya’s friendship and how much they love each other, since both were willing to sacrifice something major for the other; Maya was willing to sacrifice her own identity and Riley was willing to sacrifice her long-time romantic feelings for Lucas. But in the end, neither of them let the other be successful with it, and everything was resolved. L*caya never existed, and the writers have implied a confirmation of this by saying the triangle isn’t really a triangle.
This leads to another lesson - everything isn’t what it seems. People think Riley and Lucas are too boring, but it’s never about what other people think, it’s about what the people involved think of each other and their relationships. Maya and Lucas never had a deep connection - they had chemistry, sure, but never one where they could stay up talking to each other. The non-triangle “triangle” was all a trick leading up to one of the biggest lessons for the theme of the show, which is friendship.
