"Arrow" Season 3, Episode 6, titled "Guilty," airs Nov. 12 on The CW. This week's new episode turns the spotlight on Roy Harper/Arsenal (Colton Haynes) and his Sara Lance-related dream in Episode 5. The series also shows more of Oliver Queen's (Stephen Amell) ARGUS-given mission in Hong Kong. Meanwhile, Black Canary's trainer, Ted Grant (JR Ramirez), is accused of murder.

Spoiler alert: This update contains Arrow Season 3 spoilers. Read at your own risk if you have not watched the previous episodes or seen the Arrow 3x6 promo video.

Did Roy Harper kill Sara Lance (Caity Lotz)? In the final moments of Arrow Season 3, Episode 5 ("The Secret Origin of Felicity Smoak"), Roy wakes up from a nightmarish vision of having killed Sara with arrows. In this week's Episode 6, Roy talks to Felicity about this dream, which "felt like memories."

On a quest to avenge her sister's death, Laurel Lance (Katie Cassidy), the soon-to-be-official Black Canary, is being trained by another DC Comics hero, Ted Grant/Wildcat. Her trainer becomes a murder suspect in Arrow Season 3, Episode 6. Does she use the power of her (legal) voice to rescue her trainer?

In Hong Kong flashbacks, Oliver Queen gets subjected to a memory recovery procedure with ARGUS and Amanda Waller (Cynthia Addai-Robinson). It would not be surprising if The Arrow would use the same technique on Roy Harper. Did Roy kill Sara in a move that is related to some Mirakuru residual effect? Viewers hope to find out in Arrow Season 3, Episode 6.

Who really killed Sara Lance? Oliver Queen is convinced Malcolm Merlyn (John Barrowman) did not do it. Ra's Al Ghul (Matt Nable), who makes his first appearance on the show in Arrow Season 3, Episode 4 ("The Magician"), disowns Sara in front of his daughter Nyssa (Katrina Law).

Oliver did not think anyone from the League Of Assassins could have killed Sara. What happens next when he learns that Ra's Al Ghul believes Sara was never one of them? Too soon for all the answers. Arrow Season 3 viewers can expect more seeds to be planted for another action-packed mid-season special and finale.

Stephen Amell has been very vocal of how much he loved the production and cast of Arrow. Here is his Facebook post celebrating the show's 50th episode.
