The race is on to save Thea in the penultimate episode of Arrow season four.
The CW has released an official synopsis for episode 4×22 of Arrow titled “Lost in the Flood,” (airing May 18) which features Oliver and Diggle racing to save Thea from something we’ve yet to see (but it doesn’t sound good).
Also, Felicity and Curtis join forces with Felicity’s father, Noah Kuttler, in order to stop Damien Darhk.
Here’s the synopsis:
OLIVER FIGHTS FOR THEA; DONNA SMOAK FACES OFF WITH NOAH KUTTLER – Following the shocking events in the previous episode, Oliver (Stephen Amell) and Diggle (David Ramsey) race to rescue Thea (Willa Holland), while Felicity (Emily Bett Rickards), Curtis (Echo Kellum) and Noah (guest star Tom Amandes) join together to stop Darhk (guest star Neal McDonough).
