It wasn't from Ocean, it was fan generated by AI using Ocean's renders.
Well, we don't know if that's a stage name for a model to keep her life private. It's her name as listed on a social media app, we haven't seen anything more yet. Many people do weird things with their names. But it probably is her name.
Options: it's her mom's maiden name, to hide family connections, it's her husband's name (unlikely, because I thought she was younger than Nika/Summer/Nami when we see the flashback), she's changed her name because she's purposefully disconnected from her family...
All wild theories with no proof, but thinking about her and the sadness in her social media post... if she's still a planned LI, and she's sad about Summer, in her mind Nika and Nami have nothing to do with Summer's disappearance. Would you (in her place) date some one that was violent and caused your cousin's death?
Interesting thoughts while we wait to find out more about her. Even if she ends up a side girl (please no, we need models who haven't had Dr Ocean's enlargement bonuses), I don't think Ocean will drop her role in the story, she seems like the perfect plot vehicle to get Nika searching for Summer.
