@Xandermcc They said just that about Oliver's "death". Showrunners and film-makers blatantly lie quite often nowadays, so as to preserve the "twist" from being figured out (for example, Teddy Sears has originally denied Jay Garrick being a secret villain in an early interview).

They've definitely left the possibilities for her return quite open, and every season so far had a twist based upon some person being not actually dead (or, in the case of Flash, not who they claim to be). It's called "pattern".
