And yes cassandra x sea is a thing now!
Some things to y'all know before say

1:no cassandra isn't really Ck for real
2:sea and Becky are a whole different persons/squirrels cause Becky is afraid of Ck
3:there's 2 cassandras, casandra is the one that dates disco bear and cassandra dates sea
4:Ck's mask isn't purple it is actually pinkish red and she doesn't wear gloves
5:cassandra's tail is the same color as her furr but casandra's tail color is different of her furr's color

Conclusion:Cassandra isn't casandra, casandra is heterosexual while Cassandra is lesbian, both are from different AU's Cassandra is from an AU I stopped working on called "in-love with my enemy's sister" While casandra is from an AU called "between a mirror of fear"

AU's
"Between a mirror of fear" Is an AU disco bear makes Ck not be afraid to be herself and she marries him
"In-love with my enemy's sister" Is and AU Cassandra is in-love with sea witch was made by wolfpuppy

Don't think Cassandra is Ck cause it won't happen cause Cassandra's hero or villian name is heartless not Ck
