"A good example is when Annabeth is standing over that one river and it tells her that Zoe and Bianca died trying to save her, when in fact they were trying to save Artemis. It was Percy and Thalia's goals to save Annabeth and Grover was trying to save both."

I think in the end, everyone was trying to rescue both. I mean, Zoe never let a maiden captured by Atlas, and Bianca knows that Annabeth tried to save her, so would a type of debt. Artemis held up the sky at Annabeth, then why would not the hunters save Annnabeth? If Artemis try to help Annabeth, the hunters would do the same. And I'm sure Percy and Thalia would not let Artemis backwards. They least would not want to irritate the Olympians. And if we were in the exact meaning. Bianca died trying to save Percy, Thalia, Grover and Zoe against Talos.
