Wally trapped in Alchemy's cocoon and Barry fighting against Savitar while "Killer Frost picked up exactly where "Shade" left off was the scene that makes the audience hearts beat fast once again. 

Barry needs to dig deep and become more faster than Savitar as it shows that this villain is more powerful than him.

Thankfully, Caitlin the "Killer Frost" used her powers to freeze Savitar in his place but he quickly breaks free and flees.

This episode 7 also marked Kevin Smith's return of emotional beats to his audience from his previous work on Season 2's "The Runaway Dinosaur," which seems unbeatable for its pathos-filled hour in nailing the show's earnest tone.

The final scene reveals that Julian is Alchemy, in which to some, you have predicted this twist already.

The episode's focus shifted to heartbreaking relationship of Team Flash (Caitlin, Barry, and Cisco) tight bonds begin to break. But the question of "Why Caitlin has such a personality change?" prevails.

Obviously, Caitlin is desperate to get rid of her powers, but it seems like the episode 7 is saying that having powers can turn most people into evil.

As "The Flash" keeps unfolding its villains on this episode, who do you think is his Primary Villain? Is it Savitar? Or Is it Dr. Alchemy? Or Killer Frost?
