*spoilers ahead if you haven't seen up to season two episode five*

PREVIEW: The title alone is enough to get excited about this week's episode of The Flash.

Zoom is the big bad of season two, and judging purely by the title it appears as if we - and Barry Allen (Grant Gustin) - are about to learn a whole lot more about Earth-2's speedster.

The synopsis explains Team Flash will try to lure Zoom to Earth Prime (the original world) by having Earth Prime's Linda Park (Malese Jow) pose as Earth-2's Linda/Dr Light, last week's villain.

Does that make sense?

It sounds like a jumble but that is exactly what non-linear storytelling in this multiverse does: it allows doppelgangers to co-exist and interact, and can make for very confusing interactions (and previews).

Dr Light tried to take out Linda last week so she could survive on Earth Prime, away from Zoom's clutches.

Having been captured before she could go through with it foiled that plan, though Team Flash's willingness to exploit the scenario shows just how desperate they are.

A few more things:

- Cisco (Carlos Valdes) finally took on his Vibe moniker last week, now it's time to sort out the costume.

- Cisco also cored a date with new girl in town, Kendra Saunders (Ciara Renee). Will he learn about her alter ego?

- Harrison Wells proved to be much more direct a mentor than his predecessor (and season one's big bad Reverse Flash). Is this Wells just as conniving or is he genuinely trying to help?

- Wells and Jay Garrick (Earth-2's Flash, Teddy Sears) do not get along, but at the end of The Darkness and The Light showed they could work together. Will that continue or will they fight again?
