It could be the Golem!!! (Moira had a golem at one point, didn't she?)
I'm kidding.
I don't think we should invest to heavily in the Moira of it all, in conjunction with X-Men 97.
It should be obvious from episode one (or even the previous series) that NOTHING IS OR WILL BE 100% ACCURATE as this series is VERY LOOSELY drawing inspiration to tell stories -- just like any live action MCU property we've seen thus far.
That said, I enjoyed the very brief moments with Emma on X-Men 97.
I cannot say with confidence that I fully know of or understand any suggested bias for or against Emma that the showrunner has or had, but I never expected Emma to play a prominent role in any adapted-for-film work, beyond the long deceased Wolverine and the X-Men series.
I do hope she'll resurface.
Perhaps joining Scott in the final episodes as a radicalized mutant freedom fighter.
