Good game and story so far. I like both Christa and Jessie, I do have a thing for red heads, so it's right into my alley. The plot twist left me with many thoughts, and I doubt that Jessie is really the mastermind and former leader of a drug ring at a school. I think, her mother was it. That the mother manipulated and twisted Jessie's mind so long, that she did everything, that the mother told her, including selling drugs, "spending time" with Dylan and so on.
I saw the warning in the OP and started a new game, encountered no errors. But the choosen name was quite a few times replaced with "Jack". I could imagine, that you probably hard coded the name instead of the variable, should be easy to fix with search and replace. You will need to proofread your script though, there are some typos, I didn't make screenshots or notes about them, but they're there. Luckily nothing major, after reading the whole sentences twice, you can get, what it should be.
