PREVIEW: WHAT will happen to Dr Martin Stein?
Dr Stein (Victor Garber) is expected to be front and foremost given the episode takes its name from his alter ego.
The other half of Firestorm Ronnie Raymond is missing in action, with his last appearance being a heroic sacrifice to help Barry Allen/The Flash (Grant Gustin) save Central City.
In last week's Family of Rogues Dr Stein burst into a blue flame before collapsing for the second consecutive week.
The first appearance of Jax Jackson (Franx Demah) should go some way to answering those questions.
The West family drama is set to continue after Francine (Vanessa Williams) debuted earlier this season.
Detective Joe West (Jesse L.Martin) revealed more about Francine's life to Iris (Candice Patton) last week, and how she reacts is yet to be seen.
Meanwhile the sting at the end of Family of Rogues showed the arrival of Earth-2's Harrison Wells (Tom Cavanagh).
What is he doing in Central City?
A few more things:
- Will the writers continue to tease a relationship between Caitlin Snow (Danielle Panabaker) and Jay Garrick (Teddy Sears)?
- What is Patty Spivot (Shantel VanSanten) up to? The second member of the anti metahuman task force, Patty has also appeared to be a new love interest for Barry.
- Zoom may send another metahuman back to kill "The Flash", or will he just arrive himself? Unless he is already here....
- Where is Grodd and what is he up to?
