I remember there was a goof with Shriek’s name in the 90s, and then subsequent writers had to explain why she had two names. But that was due to two different writers not being aware the other had already named her. This Romy/Stephanie character is conceived and fully written by Zeb Wells and being one of MJ’s kids means she’s important enough to be directly connected to its mystery-box storyline so it’s not like it’s Pete’s landlord or someone unimportant.. … so, it’s amusing, but it is definitely next-level sloppy. Some blame also has to be put on Lowe and other editorial assistants for not spotting it before it went to print.
