Disciple would definitely try and convince her that humans are much nicer than Kanaya seems to think XD But she probably needs to get to know her better first. After their first conversation I think she's decided not to push her too hard - she's afraid she may already have, with Kanaya's initial reaction to her, so she may go a bit slower with talking to her again than she would have otherwise. But I'd definitely like to try and continue to build on what was started there.
