The Flash

enjoyed the mid-season finale that was on sky1 last night a lot and hope the 2nd half of the series is just as good as this first half. as for who the reverse flash is, think it's iris's bf Eddie from the future. think it's a little too obvious that it's Harrison Wells

It would be a bit shit if it was Wells imo, but the voice change would lead you to believe that he is at least a Flash of some sort.
The seeds of Eddie not trusting Barry have been planted (thanks to the present he gave Iris), so if he was then to find out he was The Flash, I think that would tip him over the edge. Thing is, if they do go down the love triangle (or square) path (square seeing as Iris has/had a thing for The Flash), then they need to be careful, as the Clark and Lana thing in Smallville got very lame and dragged on far too long.

^^^ agree the makers etc of the flash do need to be careful if they do go down the love triangle/square path of Barry/Iris/Eddie/The Flash. Hopefully they will be

Couple of little things notice how Reverse Flash never did anything to Eddie from push him, another little Easter Egg from the comics is when you see Harrison Wells wearing a Flash ring, in the comics Barry Allen (the pre 52 version) used to store his costume inside the ring.
A few more things about the current season we will see Barry developing his powers similar to his comic counter part for example being able to vibrate his body through solid matter like a wall and time travel.
I have a couple theories on the Reverse Flash, i think theres either two versions of them one based on the Professor Zoom Reverse Flash and the other the Hunter Zoloman Reverse Flash. My other other theroy is that its possibly the same Reverse Flash but from different points in time, i kinda think Harrison Wells being the Reverse Flash is a red herring as the producers didn't wanna reveal who he really was till the season finale so why make so oblivious now thats what makes the show so great .

I have to say I am loving it.... It is now officially my favourite TV show....

“Revenge of the Rogues” Description:

WENTWORTH MILLER AND DOMINIC PURCELL (“PRISON BREAK”) TEAM UP AGAIN AS CAPTAIN COLD AND HEAT WAVE CHALLENGE THE FLASH TO AN EPIC BATTLE — Leonard Snart AKA Captain Cold (guest star Wentworth Miller) returns to Central City with a new hotheaded partner in tow – Mick Rory AKA Heat Wave (guest star Dominic Purcell). The duo plan to steal a multi-million dollar painting, but Cold has another agenda while in town – to set a trap for The Flash. Snart and Mick kidnap someone close to The Flash and threaten to kill them unless The Flash shows up for a battle of fire and ice. Barry tells Joe (Jesse L. Martin) he isn’t sure he should take on Snart again after the casualties that happened the last time they fought. Meanwhile, Barry asks Dr. Wells (Tom Cavanagh), Caitlin (Danielle Panabaker) and Cisco (Carlos Valdes) to help him double his training efforts so he’s ready for the Reverse Flash when he returns to Central City. Iris (Candice Patton) deals with the aftermath of Barry’s confession, and Cisco makes the CCPD a new shield.

Former “Spartacus” star Liam McIntyre has joined the cast of “The Flash” as Mark Mardon, aka The Weather Wizard (The second one, the brother died in the pilot). He is set to appear in the upcoming 15th and 16th episodes of the series.
