However, one thing that confused fans the most was the fight where the characters appeared to be using lightsabers.
One fan wrote on Twitter: “What the hell is going on with The Flash anymore? The finale legit just turned into a lightsaber battle [crying emoji].”
Another joked: “May the Speed Force be with you!”
“Okay, I didn’t expect this #TheFlash,” someone else commented.
While another loved the ending, writing: “HOLY S**T. They really ended this season with a f***ing BANG.
“I thought last week was amazing, but this one surpassed it. One of my fav episodes since S4 tbh. What an incredibly fun ride!” (sic)
All seasons of The Flash are currently available to watch on Now TV.
