Felicity & Thea Work Together On Tonight's 'Arrow'

It looks like Thea and Felicity are working together on something big on tonight’s all-new Arrow.

In “Fighting Fire with Fire”, Oliver (Stephen Amell) faces his biggest challenge yet as mayor, and contemplates resigning from office — but Thea (Willa Holland) isn’t happy with that idea at all and goes to Felicity (Emily Bett Rickards) for help.

Meanwhile, after Vigilante attacks Oliver while he’s acting as the mayor, Diggle (David Ramsey) leads the team in a mission to stop Vigilante once and for all.

Arrow airs TONIGHT @ 8PM ET/PT on The CW.
