Is there a reason why "su" cannot mean your in this case?
that's what I put too, but I got it wrong for something else!
it could be your or his as well as her
Tedstone, Cuidado...in the barrio, it could be your or his ass, as well as hers, también. This is a great sentence.
Nope, it should accept it.
"Su" means "hers", "your" means "tuyo".
