Phew! Luckily for our heroes (and because The CW wouldve effectively killed off two of its most successful and popular shows), wed find out that Barrys earlier ghosting issues were as a result of him travelling back in time after Savages decimation of Central City. Arriving back at the moment where he, Oliver and Merlyn met with Savage, Barry reluctantly uses his knowledge of the doomed future to speak up on how their plan to take down Savage simply isnt going to cut it. When asked by Oliver about what went wrong, Barry tells him straight that the main problem was Ollie because his head wasnt in the game. It was a stark, harsh truth, but Barry was bang on point. Ollie wasnt the sole factor in the plan not working out, but he was a vital cog in the problems that arose. In last seasons crossover and in the other moments where Barry and Oliver had shared screen time, Ollie always comes across as the more senior, mentor-type figure. With this two-parter, weve really seen that Barry is now very much Olivers equal and is confident enough to call out the Emerald Archer when needed.
