\'The Flash\': Caitlin and Ronnie\'s reunion will be \'devastating\'

The midseason finale of "The Flash" features two rather heartbreaking stories for fans before the holidays. There\'s Barry finally coming face-to-face with Reverse Flash -- the being responsible for killing his mom -- while Caitlin will see her former fiance Ronnie for the first time since the particle accelerator explosion.

It\'s an extra bizarre moment for Caitlin, seeing as she believes Ronnie died in that explosion. Danielle Panabaker -- who plays Caitlin -- spoke to Zap2it about what seeing Ronnie again is like for the character, as well as the importance of protecting Barry and some karaoke coming to the show in the new year.

Zap2it: The midseason finale is the episode where we finally see Reverse Flash!

This is the biggest challenge anyone at S.T.A.R. Labs has faced yet. With it being so personal for Barry, how is the team reacting to that?

Obviously we\'re all very concerned about Barry\'s safety and well-being. Knowing he\'s so personally invested in this case, we\'re really interested in protecting him. Obviously he thinks he\'s prepared to take on the Reverse Flash, but it\'s our job as his keepers and guardians to protect him in this scenario.

What\'s especially cool about this episode is it doesn\'t just deal with Reverse Flash. It\'s also the first time Caitlin sees Ronnie since the night of the explosion.

Yes, it\'s pretty crazy. Obviously, Caitlin thought Ronnie had died in the particle accelerator explosion. However, this week she finds out he didn\'t die but he hasn\'t come back in exactly the same form that he left her in, if that makes sense.

Imagine if you saw your dead fiance. [laughs] She thinks she\'s going crazy. Her first reaction is "This can\'t be right, I can\'t be seeing what I\'m seeing." But with her experiences over the last almost year with Barry, she\'s got to think twice and look twice.

Knowing where the Ronnie storyline goes in the comics, it\'s heartbreaking but ... At least he\'s alive? It could be worse ...

I don\'t know. She has this really good line in the episode where it\'s like, "I used to play this game, what would I give in exchange with one more moment with Ronnie." When she finally gets that moment, she wishes she never had it. That\'s how traumatic it is for her to see him again.

Looking forward, is there anything you can tease about what to expect when the show returns?

I\'m really excited for what\'s next. There\'s a little bit of a tease of maybe a karaoke scene in the near future and there\'s a lot more with Ronnie being back in Central City and Caitlin\'s not quite ready for that.

Lastly, as viewers we see this whole side of Harrison Wells that no one else is privy to. We all know he\'s up to something and it looks bad. At any point in the near future will we begin to see Caitlin and Cisco begin to have any suspicions that maybe he\'s not everything he says he is?

You will start to see some of the other characters start to get suspicious. Obviously, we\'ve seen Joe is suspicious but doesn\'t have anything to base it on other than his instincts at this point. As time progresses and he shares his qualms with other characters, they become a bit more skeptical of Harrison as well.

"The Flash" airs Tuesdays at 8 p.m. ET/PT on The CW.
