12 Worst Time Travel Goofs In The Flash (So Far)
2. I Don’t Wanna Be Buried In A Pet Sematary
Then there’s the other major change that Barry knows of so far. When Thawne changed the timeline again, the ripple effect caused Cisco’s older brother Dante to be killed in a car accident only a few months before Our Barry returned to the present after making the change.
As with the other changes, we’re given no indication as to why it is that those changes had a knock on effect that caused the car accident. Just as with Sara’s disappearance, there’s no way to blame Our Barry for directly causing Dante’s death.
However, Barry deliberately caused or allowed events to take place which would have a completely unknown and unpredictable effect on the world around him. You couldn’t indict him for murder, or even manslaughter, but it’s fairly clear that, morally speaking, blame can be laid at his feet.
The question is, why hasn’t Cisco, a genuine rocket scientist, figured that out yet? He was distant and angry with Barry, but only because the Barry of that timeline had refused to go back in time and save Dante’s life.
When he does find out about the timeline change, he’s angry all over again because he considers it hypocrisy that Our Barry went back in time to save his mother after his Barry refused to do so for Dante. Our Barry talks it through with him, and the two reconcile… but Cisco doesn’t seem to understand that the new changes to the timeline have directly led to Dante’s death.
Cisco knows that A) this Barry is from another timeline and is winging it with the changes in this one, and B) this Barry was taken aback at him going to counselling. Surely it's not that hard to connect A to B and figure out that Dante wasn't dead until Thawne timef*cked the world? And of course, since Our Barry has told all his friends that he’s responsible for the new timeline, Cisco wouldn’t blame Thawne. He’d blame Barry.
Either way, if Barry thinks Cisco is narked at him now, wait till he finally twigs. It's the difference between being aggrieved that your mate won't lend you money, and being angry because your mate has stolen all your money.
