From the looks of a new teaser video, the next new episode of "Arrow" will be intense, to say the least.

The extended promo for the new installment, entitled "Broken Arrow," suggests that a number of game changing events will occur when The CW series returns on April 15. Some of the spoilers include Oliver Queen's plan to team up with the Atom, his plot to bust Roy Harper out of jail and a steamy love scene between the vigilante and Felicity Smoak.

During last week's episode, "Public Enemy," Roy took the rap for Oliver so that he would be released by the police. In the trailer for the new episode, Oliver is seen plotting to break Roy out of prison. However, another clip shows Roy being stabbed in the back during a prison riot.

"I'm going to break Roy out of prison," says Oliver before the video cuts to a shot of Roy in prison and a shank being passed around.

To the delight of "Olicity" fans, another scene from the promo reveals that Oliver and Felicity will finally hook up, despite the fact that she is still dating Ray Palmer.

"Everything I did, everything that happened, has led me right here to this moment," Oliver says in the video before Felicity enters a candle-lit room. Things then get hot and heavy between the old flames and we see shots of the couple having sex.

Oliver will also be forced to team up with Ray, aka the Atom, in order to defeat a new villain named Deathbolt.

In addition, the confrontation between Oliver and Ra's will come to a head and it seems like Oliver will eventually agree to take Ra's' offer to become his successor as the leader of the League of Assassins.

Design & Trend reports that the synopsis reads as follows:

"Lance (Paul Blackthorne) continues his mission to take down the Arrow (Stephen Amell) so Felicity (Emily Bett Rickards) orders Oliver to keep a low profile. However, when a meta-human named Jake Simmons (guest star Doug Jones), who kills people with blasts of energy and plasma, starts terrorizing Starling City, Oliver is forced to ask Ray (Brandon Routh) for help. The unlikely duo is forced to team up to save the city."

During an interview with E! Online, "Arrow" co-star David Ramsey dropped hints about what fans can expect from his character, John Diggle, in Season 4, and the development of a storyline involving H.I.V.E. According to the actor, siewers will find out why the mysterious organization paid Deadshot to kill Diggle's brother, Andy.

"From my understanding, H.I.V.E. is going to be a big part of next season's big baddie. We are going to delve right into why H.I.V.E. hired Deadshot to kill Andy and what H.I.V.E. is all about to begin with. There will be a lot of Diggle's connection to H.I.V.E. next season so stay tuned."

"Arrow" Season 3, Episode 19, "Broken Arrow," airs on Wednesday, April 15 at 8 p.m. ET on The CW.
