my game theory is actually that she went on to become the eye avatar in charge of the domain we see in mag 188 (the apartment building in london where carmen felt like her roommate and everyone on the street were always watching her)

[ID: Image one is a set of tags that read: "#Sometimes I think about her and wonder what she got up to afterwards #did her connection petter out without the web? Or did she keep her low level powers? #or did she become an avatar and we never knew because no one made a statement? #tma #tma spoilers #I like to imagine that she and Gerry’s nurse encountered each other and had the worst time about it".

Image two is a screenshot from the Magnus Archives wiki that reads: "As she laid in bed, she realized that someone across the street was watching her through their blinds. As she turned away from the window to try to ignore the observer, she realised that her door was ajar and that her flatmate was watching her through the crack. Her flatmate then chastised Carmen for being awake while she was trying to sleep. Carmen's flatmate then watched her through the night, not letting her sleep." End ID]
