Isn't that the truth? Watros has made Nina watchable. It's why I was happy to have her. I knew at least I'd be happy to see Watros. I don't love Nina either and she could easily go tomorrow (like several others) but like you said, I don't mind seeing her, and I like she's in the thick of it and keeping Sonny away from his family.
Stafford and Mo? OMG. No. I could never sit through them. Lord. We are so lucky, truly, lol, to have Watros.
And I echo others, I like Jason and Britt too. She's a taller Sam with a pulse and personality.
I liked the Carly and Liz
Yes, Bianca - witnessing the tumultuous, toxic relationship of her parents (and uncle) at such a young age (and setting her dolls on fire), already suffering an eating disorder and relentless bullying at school - developing a substance abuse addiction would totally fit.
Kendall actually had a comfortable middle-class upbringing in rural Florida, with her parents, by all accounts, spoiling and doting on her (which might explain her sense of entitlement).
While Bianca grew up privileged, with wealthy, high-profile parents (the apple of both their eyes), the emotional scars ran deep.
