Serinda Swan is coming to The CW. Or coming back, really.

The actress, who has twice appeared on Smallville in the role of Zatanna, will guest star on the fourth episode of Supernatural this season.

As first reported by Fancast, Sawn will portray a news reporter who tracks an unsettling series of suicides. Look for her character to end up working with the Winchester brothers.

Supernatural premieres its sixth season on a new night: tomorrow at 9 p.m.
