As much as I personally would want to hear an explanation, I can understand why there is a significant portion of people who wants nothing to do with Steph any more and would like to skip it.
So, even if only to shut up the people complaining about the presence of Steph, sure why not? But I suspect that will require additional "plot gymnastics" down the road as you have always envisioned her as part of the story.
The real question is, are you willing to spend the effort to figure out how to skip the explanation (and any further interaction with Steph, because the complaining will only get 10x worse if you skip it once but not later) without compromising the integrity of the story you have envisioned. If it can't be done, then I'd say too bad so sad, sucks to be the Steph haters.
But if you are doing it, the suggestion of another option for "Indifference" by
Wolf Plays™ is a good one too.
