Go Inside Arrow “Checkmate”

An inside look at the next new episode of Arrow has been released. The episode is called, “Checkmate” and it will air tomorrow, March 15.

In the episode, “Oliver (Stephen Amell) gets closer to the truth about Prometheus. Meanwhile, Helix refuses to continue helping Felicity (Emily Bett Rickards) until she does a favor for them.”

Sounds like it is going to be a good episode. I wonder what favor Helix will ask of Felicity in this episode. Any theories?
