'Arrow' Season 5 Finale SPOILERS: Manu Bennett Deathstroke Reunites With Stephen Amell Oliver Queen In 'Lian Yu'

Big things are happening as the fifth season of "Arrow" draws closer to the end. There have been speculations that the "Arrow" Season 5 finale will feature the return of Manu Bennett as Slade Wilson because, well, it's called "Lian Yu", of all things. Will Deathstroke finally break out of his island prison in "Arrow" Season 5 Episode 23? Could the former villain reunite with Oliver Queen and help him defeat Prometheus?

Manu Bennett first debuted as Slade Wilson in the third season where he was responsible for the death of Oliver Queen's mother Moira. Since then, fans have been hoping that the "Lord of the Rings" actor will return as Deathstroke and ultimately face the Green Arrow. Luckily, "Arrow" Season 5 executive producer Marc Guggenheim teased on Bennett's major comeback on Twitter. The post featured the script for "Arrow" Season 5 Episode 23, which is suspiciously titled "Lian Yu". Guggenheim made things even more obvious when he tagged Bennett in the tweet. But the question remains, will Slade be back to help Oliver or is he on Prometheus' side?

The speculations have began and fans are hoping that Manu Bennett's return will mean a good thing for Oliver Queen. ComicBookMovie has recently reported on clues as to how the "Arrow" Season 5 finale will conclude, teasing that Oliver Queen will bid Lian Yu "a final farewell". It certainly sounds like Oliver will revisit the island and get a reunion with Slade Wilson, but will Deathstroke help him as they leave the prison? Fans should keep their fingers crossed in hopes that Oliver and Slade will work together to defeat Prometheus.

Will Manu Bennett escape his island prison in "Lian Yu"? Has Slade Wilson finally decided to be one of the good guys and join Team Arrow in the "Arrow" Season 5 finale? Could Deathstroke ultimately prove that he will never forgive Oliver and help Prometheus instead? "Arrow" Season 5 Episode 23 will air on The CW on May 24.
