With every passing episode of "Arrow" Season 4, fans are getting more desperate to know whose grave Oliver (Stephen Amell) was at in the premiere episode. Although Felicity (Emily Bett Rickards) is confirmed to be safe, the rest of the Team Arrow members may still be facing fatal danger.

In the upcoming Season 4 Episode 14, Damien Darhk (Neal McDonough) seems to be going on the offence and taking the fight to Team Arrow. In the promo for "Code of Silence", a group of people calling themselves the Demolition Team is seen attacking the Arrow Cave — although they do not know about its existence.

As far as Damian is concerned, his wife Ruvé Adams (Janet Kidder) is running against Oliver for mayor and they want him dead. Ruvé's voice-over is heard saying: "Do not let Oliver Queen leave this building alive". It looks like the attack will leave most of Team Arrow injured, especially Laurel (Katie Cassidy).

As fans know, Damien is currently aware Oliver has a son, thanks to Malcolm Merlyn (John Barrowman). This has left all the fans wondering if Oliver's son would be in the grave, but that seems unlikely.

Here are our top five contenders from "Arrow" who could be headed grave-wards:

  • John Diggle (David Ramsey): He is a member of the Original Team Arrow, as Felicity likes to put it, and his death would affect Oliver and Felicity equally. His death would warrant Felicity's reaction in the grave scene, wherein she demands that Oliver avenge the death by killing the one that caused it. He has had a huge arc in Season 4, and the introduction of his brother also seems very suspicious.
  • Laurel: Laurel has had a good season as well, and she is also close to both Oliver and Felicty. Especially now, with Captain Lance (Paul Blackthorne) and Donna Smoak (Charlotte Ross) dating, Felicity and Laurel are half-sisters of sorts and closer together. Felicity would definitely want to avenge her death.
  • Captain Lance: Although Lance's death would not necessarily shake Oliver and Felicity as much as shown in the grave scene, he has been working very closely with Team Arrow. Felicty may also be taking into account his mother's feelings when she asks Oliver to go back to his killing ways. Moreover, he has risked his life with Damien Darhk in the past, and if that is how he gets killed, Oliver will take it upon himself to get revenge.
  • Thea: Although she is a likely candidate, Thea's death seems improbable because she has already defeated death twice. It would be quite unlikely for the writers to give her the same arc again.
  • Samantha Clayton (Anna Hopkins): The mother to Oliver's son, Samantha is included in the list because of what Damien Darhk knows about her. However, it is highly unlikely for Felicity to react the way she did in the grave scene if Oliver's baby mama gets killed.

While the person in the grave remains a mystery, it has been confirmed that there will soon be a "Legends of Tomorrow"/"Arrow" cross-over, which will show Oliver as the elderly, one-armed Green Arrow. This version is very similar to the Frank Miller version of Green Arrow in "The Dark Knight Returns".

Fear not: Oliver of "Arrow" is safe, the rag-tag team of "Legends" has travelled to Star City of 2046, and it is that Oliver that has a stump for an arm.
