Crisis on Infinite Earths Part 3 left the Arrowverse decimated - but could Harbinger and Pariah partner up to redeem themselves and undo it?

The final episode of The Flash before Crisis on Infinite Earths confirmed Nash Wells became Pariah in the teaser aired after Batwoman and Supergirl.

A new teaser played at the end of this week's Batwoman episode which hinted at Nash Wells from The Flash becoming Pariah in Crisis on Infinite Earths.

The Flash's Tom Cavanagh is seen dressed as DC hero Pariah in a new Crisis on Infinite Earths set photo along with his other Arrowverse castmates.

Tom Cavanagh will be playing the doom-herald Pariah in Crisis on Infinite Earths. Who is this man of mystery and why is it fitting Cavanagh plays him?
