So, I finally got a chance to watch the clip from 3x10 and it kinda threw me a bit how rude Barry was to Wally. Obviously without context it’s hard to know what exactly Wally did that had Barry pissed enough that he felt like he needed to call him out in front of everyone and essentially threaten to cut his training off (again) if he didn’t straighten up and fly right. So what gives?
Well, I went back and watched tonight’s episode again and before it got to the part where the writers ripped all of our hearts out by having Barry witness Iris dying, it showed him stopping at a TV and hearing a news report about the trial of Jared Marillo (sp?) aka Plunder coming to a close. He was found guilty of grand theft and aggravated assault after being caught by the Flash earlier that year. That video was 5 months in the future.
Well, in the 3x10 clip Wally is excited, and everyone is praising him, because he saved Barry’s life and apprehended Plunder and put him into Iron Heights. He did the ‘right’ thing and yet Barry is still pissed. To everyone else, I’m sure it looks as if he’s overreacting and just dumping on Wally. But what if it’s more than that? What if the real reason Barry is pissed is that his run-in with Plunder was his attempt at changing the future? Let Plunder ‘beat him’ and get away (for now) so that 5 months down the road there wouldn’t be a news story on TV about Plunder being found guilty the night Iris supposedly dies. Its not a big change but it’s change enough.
However, since Wally isn’t aware of any of this he comes along, saves the day, and puts the bad guy in prison–like he should. But because Barry knows the truth it makes him angry, frustrated, and left feeling helpless. If he can’t even control something as small a when some petty criminal goes to jail, then how is he going to save Iris?
