Ruby Sunday (early 20s, absolutely loves the doctor and trusts him completely, kind of naive and well-intentioned and willing to see the good even in the biggest assholes so she's easily taken advantage of), Belinda Chandra (around 30, has spent years dealing with asshole men and asshole bosses, sees right through bullshit, has no patience for it, and pulls a grand total of 0 punches when calling it out, apparently has a maternal/protective streak to her?), the Doctor (incredibly charming and smart, also carries more issues with him than the human mind can handle and is the one in nominal charge)
just thinking we coulda have a 3-person tardis team with Belinda increasingly concerned with the risks Ruby is willing to put herself through due to her trust in the Doctor, and seeing it as further proof that the Doctor is by no means trustworthy, and also trying her damnedest to make Ruby see that, meanwhile Ruby is constantly tryng to convince Belinda how wonderful and amazing the Doctor is. And the Doctor's just like, ignoring there's any tension on the Tardis at all. coulda made for a different dynamic I think
