Arrow 3.15 “Nanda Parbat” airs tonight, February 25, 2015, at 8pm and The CW has released several promo videos to heighten the anticipation.

Watch the videos here below, including two clips from the episode, along with the trailer and a behind-the-scenes featurette. One of the clips was shown during star Stephen Amell’s recent goal-fulfilling visit to Late Night With Seth Meyers, and sees the Arrow facing off against Nyssa al Ghul.

“Nanda Parbat” will also mark Brandon Routh’s debut as The Atom.

This is the last episode of Arrow until March 18, 2015, so expect some surprises tonight!

Thea (Willa Holland) is not happy with her father these days, and according to the promo videos, she’s so angry she’s ready to sentence him to death by handing him over to Ra’s al Ghul. Her fury is double-fold. One – she now knows that Malcolm (John Barrowman) is to blame for her killing Sarah (Caity Lotz), and to top it off, he released Slade (Manu Bennett) from his prison on Lian-Yu, putting her and Oliver (Stephen Amell) in a deadly situation. Now we (and Oliver) kinda understand that he is trying to prepare her for The League of Assassins, but it still doesn’t make it right. I wouldn’t forgive him either (although I wish he would teach me to fight like that).

Felicity (Emily Bett Richards) isn’t too happy along with Thea, when Oliver decides to go save Merlyn. I hate when everybody gets all judge-y, although I must say it is refreshing that Thea did not yell at Oliver when he finally came clean about being the Arrow, and gave him a hug instead. That was a twist.

UPDATE: The CW released another behind-the-scenes look at the episode, this time with Brandon Routh.
