First off: In this AU, older brother Caleb would be still alive, but he would still have been her caretaker because their mom still sucks. This means a lot of her trauma wouldn't be present and thereof she is less bitter and more of her playful but still cunning personality would shine through.

Since BLK seems to be college club, I see Ophelia major in something related to cybersecurity.

Her professors admire her skill but absolutely do not trust her. For a price she offers her hacking skills to her classmates. Of course... she would still use her skills for scams but also to collect dirt and blackmail of others.

She would most likely not have her abilities to see and hear ghosts in this AU, but have an interest in the occult (I'm unsure about taking her ability away yet but storywise it wouldn't make much sense)
