Arrow season 6 trailer:

Saw the latest Arrow episode Thanksgiving and I spared a thought for Katie Cassidy for the very recent loss of her father David Cassidy.
I am very sorry for her loss.

Season 6, Episode 7.
Given its episode title and perhaps deliberately this was aired on the actual Thanksgiving Day itself on November 23 2017.
For this episode Oliver gets arrested again this time by FBI Agent Watson for suspicion of being the Green Arrow and later on released on bail with his trial now being delayed.
If this wasn’t bad enough, Oliver finally knows about John’s condition and John going to the hospital for it.
With John in hospital, Oliver steps back in as Green Arrow and good seeing him back as the Green Arrow even if it is just this one time.
Cayden James reveals to Oliver as the Green Arrow that he holds him responsible for the death of his son but Oliver does not know what he is talking about.
This Thanksgiving episode ends on a positive note with Thea finally waking up from her coma.

Crisis on Earth-X Part 2:
Season 6, Episode 8.
Part 2 of the Arrowverse 2017 crossover.
Earth-X as revealed here is Earth where Hitler and his Nazis won the Second World War and Hitler gets to live to a ripe old age of 105 in 1994.
Footage of the real Hitler is briefly shown here.
This episode is Arrow 6.8 and there was a portrayal of Hitler in NuWho’s own 6.8 Let’s Kill Hitler.
Quite shocking that the masked man in the cell at the beginning is Earth-X’s Tommy.
It was sure a shock for Green Arrow and Supergirl to see doppelgangers of themselves as their adversaries and that they are married to each other.
Thrilling climax at the battle that saw some of the heroes getting captured and sent to a prison camp at Earth-X’s whilst STAR Labs has been taken over by the Nazis.

Arrow has been renewed for a seventh season.

Arrow season 7 will make its world debut in the US on October 15 2018.

Arrow season 7 trailer:

Arrow has been renewed for an eighth season.

It has been announced that eighth and next season of Arrow will be its last.

Crisis on Infinite Earths: Part Four:
Antepenultimate episode.
The Arrow part of Crisis on Infinite Earths.
Not bad battle between the Paragons and the Anti-Monitor.
Intriguing that Oliver is presented as the Spectre.
Sad that Oliver dies…again.
