Rosie's Links
Rosie loves Tabby in her own weird way, but also sees her as an opportunity for experimentation.
Tabby is kinda obsessed with Rosie - she loves her so much, that's why she agrees to being experimented on.
Rosie finds Sam a bother and would rather steer clear of him.
Sam thinks Rosie is purposefully getting in his way... so he doesn't like her.
