User blog:H. Mills/Caitlin Snow - Killer Frost???

In the 1st season of the Flash when Barry travelled through time to save his mother he saw Caitlin as Killer Frost.. so i was wondering is this going to become a plot for a 3rd season (if there is a 3rd season) or maybe even in the 2nd one. In my oppinion it's more probable to happen in the 3rd season than in the 2nd because they're fighting Zoom in 2nd season and it's not really necessary to complicate the things even more...

I think that another alternative is we to see her in the DC's Legends of Tommorow. Some of the heroes and the villains from both the Arrow and the Flash series will travel through time to stop Vandal Savage therefore when they travel to the future they might run into Killer Frost... Barry will be guest star in this show so he may be with them when they see Caitlin. But it was also said that DC's Legends of Tommorow will be kind of a break from the Arrow and the Flash's shows so...

It may be also possible Barry to travel to the future accidentally just like he travelled to the past in the Arrow's episode Legends of Yestarday. And while he is in the future he might see Caitlin but like Killer Frost.. Maybe he will accidentally change something in the future and this might be the reason something to change in the present which to lead to the new changed future. Or maybe Barry, already saw the future for Caitlin or someone else, will want to change it and do something in the present which will lead to consequences in the future..

This are all my theories for now. Please tell me what you think and if you have another ones.. well, i'll be glad if you share them with me.
