You are exactly right. I do get the sense she’s trying to pick a fight with me. I have refused to satisfy her with one single response in kind. The more calm and polite I remain, the more aggressive she seems to be getting. I shouldn’t have to be around her too much at work anymore now that I’ve transferred and I definitely don’t want to escalate a drama at work of all places.

Silver Trees made a great observation about being too passive though. I can try to work on some professional and assertive responses to her without making it into a conflict...

She has picked fights with other co-workers and seems to thrive on it.
