It looks like Oliver Queen (Stephen Amell) will continue to have a hard time in reuniting his team in the upcoming episode of "Arrow" season 6. Based on the latest promo released by The CW, the current and former members of Team Arrow will find themselves disagreeing with each other, as the viewers have already seen many times this season. The heated argument will pit Oliver and Dinah Drake (Juliana Harkavy), along with their supporters, into another physical battle. 

"Arrow" season 6 episode 14, titled "Collision Course," will be centered on the team's effort to search for Black Siren/Laurel Lance (Katie Cassidy). However, the opinion of Team Arrow on how to deal with Black Siren is divided, as half of the team believes that Laurel must pay for her previous actions. The other half, particularly Oliver's faction, thinks that the character deserves a second chance. While the team has a lot on its plate at this time, including the threat of Cayden James (Michael Emerson) to Star City, the original and new members of Team Arrow will find time to fight each other, according to Comic Book.

Oliver, Diggle (David Ramsey) and Felicity (Emily Bett Rickards) are on the same boat that Black Siren still has a place in Team Arrow, while Curtis (Echo Kellum) and Rene (Rick Gonzalez) agree with Dinah that she needs to get punished. The fans have seen Black Siren lost her way and ultimately joining the bad side, but the previous episodes of season 6 show that the character still has a hint of goodness in her heart. Black Siren was last seen with Quentin Lance (Paul Blackthorne) on a road trip, as the latter knows that Laurel can still redeem herself in spite of all the problematic decisions that she made.

On the other hand, Dinah wants the most extreme punishment for Black Siren as revenge for the death of Vigilante (Johann Urb). Although Oliver and his allies will not allow Dinah's faction to kill Laurel. Of course, there is still hope that Team Arrow will sort things out and settle their difference at the end of the episode, especially that there are actual villains that are hell-bent on destroying the team and the very city that they are trying to protect in the first place.
