People are going to be pissed, Lotz told EW during the filming of Doomworld.

I was like, Uh-oh, fans are going to be mad at me.

When I read it, I was like, Oh, thats harsh, really harsh.

Hopefully people wont be too mad because its not really Sara, its someone else.

So everybody calm down.

True, Felicity is still very much alive in the world ofArrow.

But how did she come to be a suited superhero in this reality?

Whats the opening scene, whats the thing that takes you to the title card?

We all recognized, Well, who are we going to use from our Arrowverse?'

Its always nice when you could pull in a character from one of the other shows.

So this is really the only circumstance by which we could do it.

Alas, shes really not on screen long enough for that to matter.

Yes, it just so happens that shes killed, Guggenheim says.

So thats how it all came together.

But I hope people enjoy it in the spirit in which it was intended.

For her part, Richardson-Sellers notes that Felicity was far from the only hero that the duo had killed.

I love the crossovers.

Despite this version of Felicity meeting her maker, is there a chance we could ever see her again?

Theres two lines in the sand that Ive drawn forArrowfor myself, Guggenheim says.

Those, to me, are two lines that I just think are a bridge too far.
