"Arrow" Season 5 back half is packed with more revelations about Oliver Queen's killing decisions and this season's big bad, Prometheus. For fans who have been waiting for the masked villain to make a scene, episode 14 is set to leave a cliffhanger leading to his grand plan.

"Arrow" Executive Producer Marc Guggenheim told Entertainment Weekly that the show will reveal the moral and psychological complexities of Oliver's killing. As per Guggenheim, there is a lot to explore about why the mayor of Star City enacted a Gun Safety Law that fans may have yet discovered.

"Arrow" Season 5 is also set to see the effects of Green Arrow's decisions to kill or not to kill on his team, Executive Producer Wendy Mericle teased. She hinted that Felicity and Curtis will face some dilemmas concerning their morals and their previous actions.

Meanwhile, episode 14 of "Arrow" Season 5 will present the beginning of Prometheus' grand plan. Apparently, this season's big bad has been planting seeds all along and the new episode will drop a key to his next move.

Apart from Prometheus' threat, MobilenApps earlier reported that Green Arrow will be arrested in the upcoming episode. He will face charges related to the death of Detective Malone.

To make things more interesting, Oliver has one more problem to attend to. Reportedly, his girlfriend Susan will be suspecting him to be the Green Arrow.

It remains to be seen how it would affect Oliver but Guggenheim already made it clear that earlier fan theories about this subplot could be wrong. The team behind the hit CW superhero series is not doing something similar to fan predictions though he didn't specifically mention what theories those were.

"Arrow" Season 5 is airing every Wednesday nights at 8 p.m. ET on the CW. For more updates about your favorite show, don't forget to visit us here at MobilenApps.
