After how things ended between The CW and Manu Bennett following his last appearance in Arrow, news of his return definitely came as a surprise. However, both Stephen Amell and Marc Guggenheim confirmed he would be coming back to the show, but did they make some sort of mistake?
A new series of Tweets from Bennett certainly seems to point to that being the case as the actor is claiming that he will not be back for Arrow's season five finale after all. Now, there are a few different possibilities here. He may be unaware that his return was announced and is pretending he's not coming back so he avoids spoiling the surprise. Alternatively, Bennett could be annoyed they're shooting Deathstroke's scenes without him and may have now decided against coming back to Arrow.
Then again, perhaps he's just trolling us all! It's hard to say for sure, but this is definitely weird and is sure to disappoint fans who were getting excited at the prospect of Deathstroke coming back to the Arrowverse. Someone who is officially returning is Captain Boomerang as he can actually be seen in the photos below. Presumably, Oliver breaks them out of prison to help him take down Prometheus!
