On Wednesday’s Arrow (The CW, 8/7c), the team travels to Nanda Parbat for some Lazarus Pit action — and, oh yes, some Oliver and Felicity action, too.

TVLine was lucky enough to attend a screening of the episode and we’re sharing some teasers about the big hookup, Thea’s fate and more.

* With his sister hanging on by a thread, Oliver is understandably devastated, leading to some great emotional moments from star Stephen Amell. You will very much want to hug him.

* While you might have already glimpsed the steamy Oliver/Felicity sex scene in the promos, know that there’s still a surprise in store next week.

* While Ollie is all for using the Lazarus Pit to save Thea’s life, Malcolm has a very surprising stand about the death-defying “magic hot tub” (as Felicity dubs it) and for good reason: The aftereffects ain’t pretty.

* Felicity’s fiery face-off with Ra’s al Ghul is well worth the wait. She unleashes a mouthful, but it’s Ra’s words to her that play a pivotal role in her relationship with Oliver.

* Diggle and Maseo share an important exchange.

* The jet scene that Amell declared his favorite of the season involves the hero sharing a story with Felicity about the five years he was away.

* As Oliver prepares for the possibility of becoming the League’s new leader, his goodbye to Diggle reminds us why the show can never have enough scenes of the two of them.

* Someone says, “I love you all the more for it.”

* That mysterious shot of a Canary-like figure in the promo? It’s not in the episode.

* Fans of action/stunt sequences, there’s a neat one involving Oliver and a car in the flashbacks.
