But shell also return toArrowas early as the next new episode via flashbacks.
Definitely wasnt difficult for me to get to that emotional point.
For sure, it was hard, but it was very real.
I felt like that was good.
It was genuine and it was real.
Though that wasnt the site of Cassidys swan song.
That was a week after.
That was the very last scene that we shot.
I didnt know that I was done.
It was a bit of a shock.
But it was good.
I feel like there was no other way that I would want it to go.
I love everyone on set, Cassidy continues.
I love our crew.
Being there for four and a half years, theyve become family.
Its hard to not go into work every day and get to work with such amazing people.
That part is certainly sad.
Again, I was okay with it.
We all came to an understanding that this was what was going to happen.
I think the shock value is good.
Otherwise I feel like shows can get stale.
It was that lack of stagnation that kept Cassidy excited about the character over the years.
I still get a little choked up talking about it because I was so excited.
I remember trying on the jacket; I had been waiting for that moment.
I think that for me was the turning point.
Obviously season 2, my character had a really hard time.
As they know, I love working with them, she says.
Im always happy to come play with them if they time-travel or what not.
For her to be remembered, I think her being remembered that way is definitely important to me.
