The Flash season 7 returns to The CW with the eighteenth episode of its seventh season. Here’s how you can watch the finale, “Heart of the Matter, Part 2” online.

This Tuesday, The Flash season 7 airs a new episode. But it’s not just any episode. No, it’s the second part of its 150th episode celebration and the season finale.

This season has seen Barry Allen make his way through Central City in the hopes of cleaning up the reign of terror caused by Mirror Monarch. However, that soon presented him with various other challenges as the birth of the Flash Forces was the result by Barry’s attempt to get his speed back and the return of an old nemesis (or, well, multiple versions of him) threatened to upend peace in the city.

Team Flash may have healed the emotional wounds that were created with the Forces but the Godspeed War could potentially do even more damage. And that brought Barry and Iris West-Allen’s kids, Nora/XS and Bart/Impulse, back from the future to help stop him.

The previous installment of the Arrowverse show saw Jay Garrick pulled into the drama as well when Godspeed came after the veteran speedster but the return of Cisco Ramon temporarily held them off. However, that was only the first part as the season finale rolls on with Barry and Godspeed facing off in August Heart’s mind.20
