'Arrow': Oliver Queen is Arrested in 'Thanksgiving' Preview

The CW has released a promo for "Thanksgiving," the upcoming seventh episode of Arrow's sixth season.

Oliver (Stephen Amell) is set to celebrate Thanksgiving with his family, but from the looks of things it's not going to be a peaceful holiday. As seen in the promo above, Oliver is arrested and from what Diggle says in the next scene, probably for being the Green Arrow. Diggle tells the team that if the criminal element thinks the Green Arrow is in jail, it won't be good for the city.

Just how not good? Cayden James, the hacker that Felicity helped break out of ARGUS last year for Helix and who got away again earlier this season returns with Black Siren (Katie Cassidy) in tow to create chaos for the holidays.

While not hinted at in the promo, the episode will also deal with the fallout of Diggle's confession at the end of "Promises Kept" about his tremors and the drugs he was taking to control them. Now that Diggle is without the drugs that keep him stable -- literally -- and the team knows the truth about what is going on with him, things may be more challenging than ever for Team Arrow. Hopefully with the episode being named "Thanksgiving" there will still be things for the heroes to be thankful for.

Arrow airs Thursdays at 9/8c on The CW.
