Canon
Because of Rapunzel and Cassandra's breaking the rule actions had caused Rapunzel's hair to grow back and Cassandra didn't want to get in trouble for it, once they learn that it was her idea to crossover Corona's border wall, the two girls decided to take it upon themselves to discover why Rapunzel's hair has grown back by seeking the help of a wizard that Cassandra has heard about.

Fanon
Like Rapunzel, both Cassandra and Varian are two of the favorite characters in the Tangled TV series that are close with Rapunzel before certain events involving one of their parents causes them to betray the Princess. After the black rocks were revealed to have a connection with the Son-Drop flower and a drop of moonlight (which created the Moonstone opal), fans had believed that Varian was going to turn out to be the human host of the power that became from the moon, which had him and Rapunzel linked together in many versions of the Moon!Varian theory turn AU, before the season two finally had Cassandra merging herself with the Moonstone opal and gained its destructive powers. While Varian was able to redeem himself during the first episode of season three. Because of the bond that both Rapunzel and Varian had with Cass, the two had tried to reach out to her in "Cassandra's Revenge", along with fans seeing the two teaming up in their mission to save Cass from herself. It may not be a popular poly ship, and is bit of a friendship ship, in the Tangled fandom, the ship still has a few supporters who want all three of them to be friends again.
