ERNIE HUDSON (“GHOSTBUSTERS”) GUEST STARS - After the Ninth Circle delivers a major setback for Team Arrow, Diggle reluctantly reaches out to a Four-Star General of the Defense Intelligence Agency (guest star Ernie Hudson) for help, despite unresolved tension from their past. Meanwhile, Oliver discovers a piece of information that he believes will turn Emiko against the Ninth Circle. Alena (guest star Kacey Rohl) returns with an interesting proposal for Felicity.
Biggest surprise this episode was that Felicity wasn’t/won’t be the one who (will) release(d) the Archer program to SkyNet Star City. It’s (going to be) Felicity’s friend Alena, isn’t it?
Diggle’s stepfather is General Stewart. If he had adapted his stepfather’s surname, then he would have been John Stewart.

ARSENAL RETURNS TO HELP THE TEAM - When they learn of an upcoming attack on the city, Team Arrow calls Roy Harper to help them stop the Ninth Circle. However, things go awry and there is massive collateral damage. As Captain of the SCPD, Dinah investigates what happened in an episode that takes on a true crime narrative and tone.
Oliver and Roy (and Dinah) dropped several random mooks before encountering the guards, yet the SCPD only cared about the latter?

I don’t think thge Mooks were KILLED, just dispatched.
When we say Roy rage, I did think Mira-Kuru, but the lazaras Pit made perfect sense.
There were no future scenes

This latest episode was weird and I really didn’t like it. They parachuted in Harper for no apparent reason and used him for a plot that made no sense. It was kind of painful to watch. Arrow has overall presented challenging complex plots with plenty darkness, but at least until now it has stayed pretty coherent. This last episode, though, doesn’t fit with the season’s plot arc and doesn’t advance any of the story, in addition to being depressing and frustrating. They’ve stuck themselves into a problem that will be hard to pull out of and isn’t even interesting, and now their moral compass is completely out of whack.

OLIVER IS PUT TO THE TEST - Oliver finds himself in a precarious position. SCPD shows up with a warrant for Felicity.
The future segments seriously undermine any dramatic tension for what we see in the present. Case in point: we’ve already seen Roy in the future, hale and hearty. So when present Roy jumped into a cloud of benzene, we already knew that he was going to make it.
The bigger problem is that, by showing us a craptastic fate for Star City, the flash forwards have undermined the entire series. Oliver’s fight against crime and corruption will have come to naught, and the Archer program is going to throw a blanket of anti-vigilante oppression over the city. In other words, Oliver will have failed this city.

FAMILY TIES - The battle between Oliver and Emiko comes to a boiling point which brings back some familiar faces and leaves others in dire jeopardy.
Not the series finale, there is a 10 episode season 8. Guess Oliver has an excuse for not saving the city – he’s off saving the Multiverse. Will SA be in season 8?
According to IMDB no more Felicity.

This certainly felt like a series finale, didn’t it? The central character is leaving, so let’s all say goodbye. I’m talking about Felicity, not that guy who occasionally shoots arrows.
So is next season going to Oliver Queen … IN SPAAAACE?
