A FEW YEARS LATER...
Narrator: A few years after rescuing the Star Sanses, the girls chose to go their separate ways.
Blossom became a Star Sans and protects the AU's alongside Dream, Blue, and Ink. However, she misses her sisters, and wishes that they will meet again in the future.
Buttercup, on the other hand, has moved in with Classic Sans and Papyrus, but other than that, her life remains a mystery to this day.
Bubbles became a protector herself, but had an encounter with Horrortale!Undyne. She survived, but now is half-blind. But as for the rest, well, it's history at that point.
New adventures await the trio, but the memories they had while they were together will still remain.
