The trailer for The Flash season 2 is out and there are a lot of spoilers. You can hear the voices of different characters of the serie. There are really nice stuff in it... I think season 2 is going to be much better than season 1. You also hear the voice of the original Flash Jay Garrick...
1. New speedster
Is it a villain or an ally? There are only rumors about it, some say it's the future flash and I heared someone talking about the black flash. There is also a chance that it is Professor Zoom etc....I heared a lot of different speculations. 1 thing I know for sure, that it will be awesome to see it in the serie.
2. The vibe
Cisco learns more about himself, in the trailer you hear him saying
"What...What's happening to me?"
So he might train his powers too in this season? We maybe see more personal things about Cisco, knowing more about his past. Will he has a crossover sometime with Arrow? All things we don't know yet, but that we probably want to see.
3. Caitlin will leave the team
"I can't go back Cisco...I can't..."
What will happen with her relationship with Ronnie Raymond and why isn't he in Legends Of Tomorrow? Will we see her alot? And above all, will she use the secret of Barry Allen? Because she knows that Barry is the Flash, also where they hide.
4. Jay Garrick
I don't know who says it, but I think it is Joe...
"Who the hell are you?"
"I am Jay Garrick and your world is in danger."
It was already confirmed but still...The original Flash is coming in the Flash, his helmet already made an entrance in the final episode of The Flash. When the Time Wormhole was open, the helmet was thrown into Barry his world. Since that point, we knew...we will see him and that's just an awesome though. Will we see his original costume? Or would they make a different costume? (Probably they will stick to the original).
5. Harrison Wells
At 1:13, you will hear Harrison Wells his voice and he is talking to Barry Allen.
"You were never enemy Barry ...I'm not the thing you hate."
You also hear him in the start of the trailer at 0:15.
"I'm going to give you the thing you want most Barry...But it won't matter...Because you'll never be truly happy...Trust me, I know you and I'm always right...I'll still win."
So it will be awesome to see tom cavanagh back, he did it perfect (my opinion though) I think, he won't be back as Harrison Wells but actually as Eobard Thawne, but how? He was deleted from existence...
Tell me what you think about it :) and all your ideas.
PS: sorry if it isn't a good post, it's my first.
