Contains spoilers from The Flash Season 6, Episode 8.
Barry Allen may have spent this season of The Flash convincing everyone around him that he was processing the news of his imminent death well and that we should all be focused on helping his Team Flash friends and colleagues come to terms with it instead, but it appears that this isn't all that true after all.
Yes, last week's installment, 'The Last Temptation of Barry Allen, Pt. 1', delved deep into the Scarlet Speedster's psyche - a result of him becoming infected with Bloodwork's disease - and highlighted just how desperate he is to live. And while nobody could surely blame him for feeling that way, this desperation led him down a surprisingly dark path.
But that was only the beginning for what we're now calling Dark Flash because this week's offering, the predictably titled 'The Last Temptation of Barry Allen, Pt. 2', highlighted the impact of Barry's moment of weakness and how, in spite of his newfound immortality, he has somewhat died inside. The urgency of his rampage made for a thrilling edge-of-seat adventure that successfully managed to set the stage for Crisis On Infinite Earths.
