Arrowverse Crossover: 10 Most Awesome Moments From 'Invasion' (Part 1)
7. Oliver's Speech
Another of the dramatic arcs of the episode comes from Future Barry, who has left a recording warning the others he's not to be trusted. It results in him coming clean to everyone about changing the timelines, though the full meaning is yet to be discovered.
What it does lead to, though, is a crisis of confidence from present Barry in himself and the future. That means it's up to Oliver to stay behind and deliver a rousing speech to get him out of it.
Stephen Amell is strong throughout the episode (which often goes without saying nowadays), but he delivers this really well, especially the "You're not a God" line. It's important that, within an episode full of action, it finds time for these character beats, and it's a nice reminder of the bond that's developed between the pair of heroes.
