Arrow Season 4: 5 Ups And 6 Downs From 'Canary Cry'
6. Barry's Speed
I know that Arrow and The Flash are two shows that don’t necessarily run in line with each other, but it still felt a bit silly to see Barry Allen use his superspeed as he leaves Laurel’s grave. After all, over in The Flash, Barry gave up his speed in order to save Wally West and is still in the process of working out how to get his powers back.
Even if The CW’s DC-based shows don’t always operate within the same timescale, it would’ve saved any confusion by just simply not showing Barry leave the grave at all. It wouldn’t take much to just not show his superspeed.
You could say that maybe this took place before Barry lost his speed, but then surely we’d have had at least some passing mention of Laurel Lance’s death in The Flash? That’d be one of the problems of writing/showing a scene in advance and then having to build round it.
