I’m failing at answering the opening questions, but I still have some thoughts in regards to Red/Ruby’s character in both worlds.
In FTL, Red comes across as naive and has a childish innocence to her—she’s almost very dreamlike. She’s repressed, basically—both physically and sexually. She wants to leave Granny and prove herself in the world. As we know, Granny’s terrified of Red living a life because of what she thinks Red is capable of doing, which is kill people. But Red doesn’t see that until the end when she understands who she is.
In Stroybrooke, Ruby is, in some ways, similar to her alter ego, but also different. In Storybrooke, Ruby is not sexually repressed. Rather, she flaunts her sexuality and gets other females, like Ashely, to try and be a bit more sexier. Ruby, though, lacks the confidence that Red has. Ruby thinks she’s capable of doing nothing until Emma proves otherwise. What Ruby does share with Red, though, is her dream to be free and do what she likes, until at the end she realizes that what she loved doing most was working in that diner and being with Granny.
Okay, those are my thoughts. Hope they made sense. I feel like I had some more things to share, but I totally forgot half of what I wanted to say 😆
