Grant Gustin delivers one of his funniest performances to date in the season 7 premiere of The Flash.

After six seasons ofThe Flash, the line “Run, Barry, Run” shouldn’t work.

(The science mumbo-jumbo is on another level in this episode.)

But Nash isn’t ready to die and storms off to figure out another way for this to work.

Anyway, once Chester finishes the equipment, Allegra transfers the particles back into Nash’s body.

Overall, I thought this was a solid start to the season, given everything working against the show.
