Its not how she is trying to define herself.

Its a really hard thing to handle, especially on a show like this.

Were obviously dealing with a very real problem, a terminal diagnosis.

But our writers did such an incredible job.

Was that a possibility?

I dont think we really talked about losing her powers.

In terms of magic, this whole season Cassandras been very pro using it.

Shes always just really embraced it and been attracted to it.

And this episode, we see such a powerful reason why.

Part of her belief is tied to that.

I love John Larroquette so much.

He is one of my comedy heroes.

I watchedNight Courtgrowing up.

He is the most wonderful person to work with.

And I think hes super sexy.

When people started asking me who I saw Cassandra being shipped with, I was like, Jenkins.

I was sort of half-joking, half-serious.

It all fell into place.

But also this idea that he has everything that she doesnt.

She is going to die, and hes going to live forever.

And to turn to him seems, to me, so logical.

I would turn to John Larroquette to save me any day.

He does save her at the end there.

He says he cant do anything because of these feelings that he has for his long-lost love.

He does save her and get her to the hospital.

In a way, he is her knight in shining armor.

Ill still always love John Larroquette.

Do you think thats something Cassandra might pursue in the future?

Or was this a one-off thing where they had this brief time together?I dont know.

That relationship, to me, was so beautiful.

Cassandra says to her at the end, You did save me.

Didnt see her illness.

Just saw her for who she was, and reached out and made a real emotional and loving connection.

I hope people feel that at the end of the episode, too.

It also parallels what happened with Flynn and his vampire girlfriend.Exactly.

Way to take it back!

For Cassandra one of the things is theres this whole new groundedness to her.

Theres a focus there now and a readiness to really commit to that.

Her battle is over, but the bigger battle has only just begun.
