Snow Zane wasn't actually mocking Carson Flores; strictly speaking, it was just a kind-hearted tease.
After Snow Zane met Carson Flores, she personally witnessed or heard about the things Carson had done recently.
Firstly, borrowing a sword from the City of Netherfire, coming to Ice Snow City to seek the Snow Spirit Ice Crystal, was all for a friend.
Secondly, searching for the Soul Separation Technique was for a friend.
Thirdly, he saved Ilvarion Arnold's life, worried about his safety, sent him back, and is now actively finding ways to ensure he remains out of danger.
Fourthly, after being framed by herself, Carson's first thought was to sever ties with the Dragon Mountain Sect to avoid implicating his master, Floating Cloud, and the sect.
Several incidents piled together made Snow Zane, whose heart was as cold as ice, unable to help but admire and have a fondness for Carson Flores.
