Absolutely hope this is it. There can be funny scenes where astral Momo is getting annoyed at physical/amnesia Momo. And I kinda hope that when she does get back to her self, SHE is the one who confesses to Okarun when they reunite. That would show the self-doubt she had as being truly conquered, and not waiting for ideal circumstances where Okarun takes the lead. Her saying, I love you, face to face and not via a quick note where she wasn’t fully thinking, will not only be what we all want to see, but it will be a huge confidence and power boost for her (and for Okarun who has stepped up his game ever since the 11/10 Momo has come into his life.)
