"Arrow" season 4 could see some huge changes to the lives of the characters.
According to Design N Trend, fans want to see some new storylines when the show returns to The CW early next year.
One of these storylines has something to do with John Diggle and his brother Andy.
After years of searching for his brother, John resigned himself to believe that he's already dead.
However, in season 4, it was revealed that not only is Andy alive; he also happens to be working for Damien Darhk.
In the midseason finale of "Arrow" season 4, John tried to convince his brother to go back to the good side, but he refused.
Fans believe that this isn't the end between the siblings. Fans believe that John will continue to convince his brother to stop teaming up with the villainous character Damien.
Meanwhile, "Arrow" season 4 could also feature a twist in the life of Felicity Smoak.
In the last scene from the fall finale episode, it was shown that Felicity was shot multiple times by a group of masked men.
There are rumors that Felicity may have been killed off, but this is highly unlikely because she is one of the major characters on the show.
On the contrary, there are also some rumors that Felicity will survive and she will become the Oracle.
After being resurrected from the Lazarus Pit, Felicity will develop some abilities that will make her an even fitter member of Team Arrow.
"Arrow" season 4 will return to The CW sometime next year.
